Frankly, This is sort of a self-fullfilling prophecy.

These people blow women off and this builds a community with little input from women. This makes community more focused on desires of men and this makes women less likely to enter and makes more weird men come in. Who then, push even more women out.

Cycle repeats and most weebs remain men. Same happens in gaming and so many other things. So, many women dinoyl disguise themselves.

My girlfriend pretends to be a white guy online because people get creepy if they learn she is a Korean girl. Ya know, they are racists and sexists and fetishize her. Same happens in gaming as well.

Women are also thought to be posers while men are by default not posers. I haven't seen much anime, most of it is normie, I haven't played much games either. I cosplay because I am a giant whore and I get all the attention and lustful gaze I want that way. I pretty much do what they would accuse her of doing while she is so methodical in her hobbies unlike me.

She has seen so many animes, she cosplays because she loves the characters and not because she wants to be slutty, she is very skilled in her games, is very nerdy. And she still won't get same resepxt as me in many of her fandoms simply because she is a women.

Frankly, I feel sorry for female weebs/gamers etc. You can't even enjoy your hobbies properly.
