Well, sure, those things exist. What I'm getting at is that the % of it that happens purely because I'm -male- (or another natural property about me) is basically zero. Either they're just being belligerent in general or they perceive me to be underperforming (rightly or wrongly).

Whereas when I play with women who e.g. use a mic, very frequently it's like a switch gets flipped and people start being weird, overtly sexual, or just flat out insanely critical of every little thing the female players do. If we start losing the round (in e.g. Overwatch), they start blaming the female players unfairly, etc.

Obviously this is all anecdata but from everyone that I've spoken to it's a very common experience, hence most of my female friends just eschewing the mic entirely or only playing with specific groups instead of general matchmaking.
