To answer that question it’s a weird sort of reverse sexual puritanism – But where as puritans were concerned about people falling onto a slippery slope and committing sin, SJW’s I think are mad at… Not being able to compete with fictional characters.
It’s an issue of self-image: They think they’re ugly (and they do have ugly souls), so they deliberately make characters uglier so they don’t have to feel as bad about themselves.
I think that can be an indicator of a person’s character – You can look at someone of the same sex and recognize their attractive value to the opposite sex and sort of respect/admire that and decide to put in the effort to look your best, too. Or get mad and drag everyone down to your level so they’re as miserable as you are. Fictional characters will obviously have idealized body types – I mean, no-one’s exactly going to project themselves onto the hero if they’re a giant pudge ball scoffing down thirty hamburgers and clearly have bad hygiene.
Anita (and women like her) complaining about boobs is just a massive cope – They think fictional women having massive bazoonka’s is what’s keeping them from getting a boyfriend. When it is most assuredly not that (trust me ladies, it doesn’t really matter what rack size you have: As long you’re not severely underweight or overweight you’ll find a guy who’ll be into you).
