On the internet, nobody knows you're a dog. If you want to do something cool, I don't care if you're male/female/nonbinary/black/... You can be an purple with orange speckled snail, for all I care.
Now I've seen how e.g. some female gamers were treated, and it wasn't pretty. You should be able to play a game online, without being invited for sex or screamed at every few minutes. That kind of behaviour is very clearly not OK.
But neither is it OK for people to scream their sexual preferences around and demand my attention for it. Go ahead, fuck with who you want, but leave me out of it. Give me the permission to not care about your gender identity. Starting to scream at people because they think 'people who menstruate' is ridiculous, that's also not OK.
So please, do something cool, react if you notice something not OK. But also care for individuals, leave room for multiple opinions and don't start a witch hunt for any minor or even imagined faux pass. Live and let live.
