I agree on some points that you made here, but I feel you are looking at this just from one side.
Yes, a lot of people will flame you just for being a girl, but it's not because you are worse at the game or smth.
Whenever there's a girl involved in the game there will be 3 kinds of guys:
1) The cringey people who don't know how to act around girls and will just start flaming you. As felx said -
2) The people who will start flirting and dripping over you
3) People who will just not give a shit.
I see you're complaining about the first type (even tho Im 100% sure you met the other kind of guys, but you're just focusing on the negative side) , but not all the guys are the same and you'll meet type 2 / 3 people even more than type 1.
Also a lot of dudes get trashed for no reason too, it's a game stop caring what people on the internet thing about you.
That is absolute bullshit and I can vouch on this from my own experience, 2/4 my arena partners are girls. And as probably half of you know Im getting carried the shit out of me in arenas.
I see a lot of english community people flaming russians etc. But in reality english community is the toxic one here. They are looking for an opportunity to make drama out of nothing and they'll just try to evolve that into smth bigger because they have nothing better going on with their real lives. That's just how it is here. I have made a thread about this in the past, people agreed on this, but nothing changed, so don't expect shit to change after this either.
TL;DR
1) You are getting treated differently as a girl, but you're not only being flamed, I've seen too many cringey fucks dripping over girls on the internet to feel any pitty towards you
2) On this server every1 gets flamed, you shouldn't give much of a shit about what people on the internet thing
3) Community is toxic af, but there's nothing you can really do about it, because most of these fucks are just jobless virgins trying to make their internet lives more interesting than the real ones.
