I don't think anyone should be shamed for private/personal preferences.
If you win you win, if you don't then what harm does it do?
Perceptions of attractiveness can vary according to what group you are in ( male perception of attractiveness is different to female, class and culture etc). So I wouldn't write certain people off.
And of course behaviour standards and boundaries SHOULD be asserted.
I mean if someone wants to never date anyone apart from a 5'8 androgynous redhead from Stoke, or a member of One Direction/Blackpink that's 100% their right and does no harm.
If you can't find anyone who floats your boat, and just quietly get on with life, good for you.
I've personally found trouble with those types who have experienced loads of rejection, get angry, obsessively latch onto someone they THINK is their romantic level and try to decieve/manipulate a relationship out of them.
It's not like admiring a celebrity on a poster, it's like harassment.
For them, enthusiastic consent and what the OTHER person wants doesn't exist.
And it's painful for everyone around including themselves.
For example, guys with kids (not unattractive but fairly "mid-range" ) who think they are entitled to fish in the pond of "younger childfree women" and be treated as if they were childfree.
Some of them simply can't fathom many childfree women would rather not be dating than playing stepmum, and they need to aggressively "trick" or "correct" them into wanting the set-up.
And of course if you said "well here's a nice woman your age, with her own children", they don't want HER.
Or women who try to aggressively "befriend" guys or take over social groups they are in, to pressurise them into a romantic relationship
Julia from Nighty Night definitely walks amongst us!
I've been in a couple of environments where this has happened and it's hell - you can see the guy looking vulnerable and uncomfortable but "not wanting to be a dick" and the woman treating him like a "faux-boyfriend" without his consent (and being vicious to any woman who he might actually want to talk to).
Or agree to have casual sex then try to turn it into a relationship, then claim the guy treated them badly
I think it's to do with self-acceptance and validation as well.
People who want to enthusiastically date me reflect me back at me (hands up for the "slightly eccentric introverted lower-middle class geek" dating league).
If its not easy or I'm trying to be someone I'm not or have to do the chasing then I'm probably overreaching!
I (sometimes) look fine and scrub up ok and sometimes even get invited to posh places.
But I couldn't seriously attract a sociable mega-successful type as that doesn't reflect the lifestyle choices I've made, they'll be seriously dating women in their world.
I mean maybe they'd take me for dinner, but then it would be "we're all going ski-ing next weekend, why don't you fly up first class with Binky and Sebastian for the afterparty" and I'd feel like "oh fuck, there goes my mortgage for a year".
