Well FTR there IS sexism in gaming, for example... I remember hearing about some girl being boo'd or something at an Esports League of legends tournament (or somthing like this) like a year ago or so.
At least the NRS community seems way more charming and welcoming but even then we've still had issues with certain players cat calling women in stream set-ups at tournaments and there's vidos of top Capcom players literally grabbing a woman's butt out of the nowhere. Not to mention stream monsters over sexualize women on streams at tournaments like they've never seen a woman before and they are just extremely nasty. Harassing is NOT OK at all and that only proves that men need to stop over sexualizing women, because that is sexism, at least don't be a jerk and act all stupid about it, if you like some girl... Go talk to her nicely and it's up to her if she wants to meet you or not, you don't have to act like a fool in front of your male fellows to feel validated and making her feel uncomfortable and unsafe in the process.
I do think we are closer and closer to women being able to attend tournaments but stuff like this is just very annoying to watch, I really wish both men and women could just go to tournaments to play (because that's literally what everyone there is there for) without women having to worry about being harassed or not getting as much respect as men for doing well.
When we get to that point I'm pretty sure there won't be any need to say stuff like you're about to fight sexism or anything like that, but just when we are all seen as players. PERIOD. not female, male, gay, straight, cisgender, transgender, black, white players, just PLAYERS and PEOPLE.
