Amy Schumer's problem is that she's just kind of an asshole.
Physically speaking she's on the heavy side, but if she dressed sensibly, had a decent atitude and was nicer even if she wasnt famous she could probally get a decent guy.
Zoe Quinn has average looks what makes her disgusting to you is that you know that she's a preditor, a horrible human being that destorys other human beings lives for attention. This is a woman who successfuly preyed on lonely creative types and destroyed their lives and caused one of them to kill themselves.
Society does a pretty good job at warning women about male douchebags it does a shit job at warning men about preditory women.
