Not only weight, have you seen what they say about other girls' faces? She's disgusting, her nose is too big, her face is too long, her lips are too thin etc. It's not like you can change those things naturally and then when someone shoops themselves to "correct" these things they shit on them even more.
It's so dehumanizing, they don't even see these people as people, but as dolls or images, I mean don't you have friends who look average? Do you shit on them because they're not model tier? You don't, you see them for who they are, people with their own lives and personalities, who have more worth than just their looks.
sorry for off topic rant. It just makes me so angry
