As an older man who's a gamer, I've played enough online video games to know that a whole lot of men, or worse, boys, don't exactly conduct themselves well when there's a female in the room. Plain and simply, they just don't know how to act. Sometimes it's a matter of childish sexist remarks, and others it's like they just discovered they have a penis and here is their reason for having it. It's sad and embarrassing at best, so it is no strange wonder to me why they might want to reduce all possibility of that kind of foolishness by playing with other females. I'm honestly amazed at the amount of people that seem to have a problem with it. To me, if you're one of those people crying and raging about it, you are in all likelihood one of those people that just don't know how to act and part of the reason they want to play in their own clan.
