I can definitely see the appeal of brats (across age groups, because I prefer girls/women who have at least started puberty) or superficially (maybe I should say relatively, but not necessarily 'superficially') antagonistic girls/women and have fantasized about bratty 'dominant' girls but I can't relate to finding shy, nice girls boring. When I was in the second grade I would daydream about comforting a (fantasy) girl who was being bullied because vulnerability triggered my paternal instincts. I am turned off by over-the-top malice, callousness and cruelty (softcore antagonism is something else, something you might find in a scripted villainess who is written in such a way that she can be otherwise likeable or at least not super off-putting. I guess the line is arbitrary). I am not saying this to vent, to put people down or to be self-righteous, it doesn't even cause me anger, frustration or disgust at any given moment (I say it's a 'turn-off' but most of the time I mean it's boring and impossible for me to connect to that kind of a person emotionally), it is just a deep-rooted preference, but what really turns me off to the point of being a deal breaker is intentionally ambiguous communication of disrespect or sadism/schadenfreude via hinting or innuendo, or apart from the actual information communicated they are callous to communicate it or they're trying to emotionally provoke someone. I cannot put into words how unattractive it is to me (intentionally ambiguous communication but especially when it's sadistic or callous, even when it's neutral to some degree), this is just core to my personality (I don't know if there's anyone else like me or why I'm like this but I've never come across an adult whom I have interacted with for a significant length of time whom I could believe never engaged in the kind of intentionally ambiguous communication I have in mind. 'Passive-aggressive' covers a lot of it, although a lot of it isn't 'aggressive,' but that also refers to behavior that has nothing to do with the kind of hinting or innuendo I have in mind even if it's in some sense 'indirect'). It might be part of why it's easier for me to overlook some level of cruelty in fictional characters because they're scripted to be straightforward and open in how they communicate. I just cannot be emotionally intimate with someone who communicates with me in this "I'm saying this but technically I'm not saying this" way, it's undesirable to me.
I've never been able to relate to the idea of nice women being boring. On the contrary, the people who are consistently 'pro-fun' want everyone to be happy and those are the people I find 'exciting' (I hate saying that people are 'boring' or 'exciting' because it's as though you're reducing them to objects of your own feelings, or maybe I'm just sensitive about being conventionally 'boring' myself because I guess you can find someone's personality boring and still want them to be happy). Again, I can't put this into words (frustrating because I don't want to waste the day on this). The ones who are vindictive and mean and sadistic are almost 'uptight' to me, in a way (not that I'm turned off by nice 'uptight' people, again, I'm searching for the words), so are the ones who are 'judgemental' or negative (I mean the ones who are disrespectful but broadly anti-happiness in different ways; they critique people for how they dress, they critique them for things that don't hurt anyone or deprive anyone of happiness, they critique porn-on principle; not because of an effect they believe it has, they criticize age-gap relationships, they critique adults for playing with toys, they critique people who cosplay; I'll think of more later, they are constantly trying to take away some source of happiness for someone but not in the service of greater happiness or harm reduction). The free-sprited, laid back, charismatic types are 'never' cruel, they sympathize with everyone, they don't have to put people down to feel good about themselves. It's so much easier to sexualize and fantasize about genuinely nice women. So far this has been a complete fail, I'm not going to effectively express what exactly I have in mind or in detail.
I also have a fetish for “evil” kids. Kids who murder, kids who rape, kids who are just plain menaces to society.
I have to say, I find this brutal. It's not that I couldn't fantasize about a woman who has killed, raped, etc. but it's a 'despite' thing for me (and at some point, determined by my own self-serving arbitrary standards, I just couldn't sexualize someone who meets a certain level of cruelty or has a harsh enough personality, depending on my mood at least, and I don't mean because of deep-burning hatred but because cruelty/lack of sympathy is just an attractive personality trait to me). On some level I can understand their doing bad things playing a role in your interest in them but more so because intimacy with them is unexpected ('forbidden,' if not by 'society' than by your natural response to them when you're not in a sexual/romantic mood; or maybe that applies more so to adults since it's probably easier for most people to forgive children) or because you want to be uninhibited and feel that no one you're physically attracted to is off-limits and not because what they've done per se or being the kind of person who can do that to people per se is attractive or appealing. Maybe that's where you're coming from and I've misunderstood you.
and personally if that EVER happened to me I would not be reporting it thats all I will say.(unless the boy is ugly)
I also find this brutal, and even though I don't think I ever really paid attention to red-pillers who would talk about women being offended when hit on by an unattractive man but grateful when hit on by an attractive man (circumstantially, I'm sure there is some truth to this) it reminds me of the kind of women who will talk about creepy, immoral old men who will hit on young women and their age is a factor in why what their doing is objectionable and it seems to me that it's just about the disgust factor if they're less bothered by young men doing the same thing (I doubt they would care as much if some medically unusual 70-something-year old was indistinguishable from a man in his 20s). It's fine to not find everyone attractive but that has nothing to do with ethical principles that should be applied equally across the board. After all, that kid could hurt someone else. Then again, you are probably just joking.
I have also been turned on by the idea of sexually aggressive, 'rapey' girls/women who have some stereotypically male attitudes about sex (i.e. blackmailing me into sex, telling me I have to have sex with them or else, I also sometimes daydream about these comical rage flirting scenarios with women although that's not exactly what I have in mind; that's more romantic)- I want them to be affectionate but also to have this attitude that they can have sex with someone they despise (I'm not interested in 'hate sex' and don't really believe in it but the idea of a woman who goes against what's expected of her, as a woman, in being so 'unromantic' and not 'prissy' about sex. I've already wasted so much time on this post trying to explain my mind), to not save face about who they're attracted to in the face of rejection ("I don't give a f!#$, I'd have sex with you if I could," or "I hate your guts but I'd still let you smash/cuddle after hot sex," completely prideless), etc.
Edit: I'm also, at times, turned on by the idea of softening a racist woman but this would be a good example of how I might feel differently about a fictional villainess vs. real life people (in real life, being passive-aggressively racist or ethnocentric would be a huge turn off, especially if it's from 'liberal' women, and the kind of overtly racist queen I have in mind wouldn't be uber callous or harsh. Again, the lines are arbitrary). Being called a 'dirty n!#$er' in anger by someone who later wants to kiss me/allows me to kiss her, or as roleplay during sex/when we're about to have sex, could be interesting. I never thought about a racist child, but I think that's related to 'brattiness' (disagreeableness, anyway).
