The former. If you're not convinced other peoples reactions to what you say matter, then try making dead baby jokes in front of someone who's had a miscarriage.

As for the latter, I would suggest instead that more women are driven away from the gaming community because of online encounters. People can say "oh just ignore it" or "grow a thicker skin", but with that reaction eventually you'll have a community of just male gamers who don't mind being told they're going to be raped while playing a game.
