I am saying that women who have lots of piercings and tattoos are less attractive by old-fashioned beauty standards, and therefore, maybe, by having an alternative look young women might get less unwanted attention from old-fashioned / older men. In many ways I subscribe to old fashioned beauty standards.
Such a look is probably adopted as a fuck you to boring mainstream society, and because of personal taste, but it might just have an added benefit in putting off some boring old men who'd otherwise perv.
I would not be surprised if young alt-women's experience was that boring old men dislike the look but perv anyway.
To be clear I hate tattoos on men and women, and I'm not keen on earings let alone other piercings. People are welcome to do what they want, I know society is changing and pretty much all the yung people I meet seem to have tattoos. But I don't need to like it if I don't want to.
There is an irony in that I have, in my younger days, worn outfits which were less mainstream that the alternative look OP described is today... but I have never seen the need to mutilate or vandalise my body in order to look unusual.
I have to say that I think of tattoos a bit like I do the trans extremist movement - it's all the fashion, and you can't say a bad word against them!
"Tattoos and piercings make you less likely to have offensive male attention but that will be replaced with male abuse?"
I wondered if there was any correlation between how stereotypically attractive a woman chooses to present herself and how much unwanted male attention she gets. I also wondered if "alternative" looking women find that the unwanted male attention is reduced and it is replaced with abuse instead (eg you get a punch or a load of verbal abuse for looking like a goth instead of getting wolf-whistled for looking stereotypically attractive).
I suspect men can be arseholes whatever you dress like.
"Do you think it could be that rapists / abusive men don't actually care how little piercings, tattoos, and clothes you have?"
As above - when I said abuse I was referring to being punch or verbally insulted - not rape, sexual assault or sexual abuse.
"And men who crave attention and enjoy catcalling / beeping / sleazing on women will do it wether they're in school uniform, gym clothes, or stockings and suspenders? Pink hair or not."
I feared that might be the answer.
