I submit that there are also women with difficulties socializing in person who spend a lot of time on the Internet too,
There are, but they hate the guys in fedoras.
Goth girls (Sorry about the confusion!) like goth guys, and vice versa. Foreveralone guys, on the whole, would like foreveralone girls, but foreveralone girls outright hate foreveralone guys. The foreveralone for women subreddit for example has blocked all members of regular /r/foreveralone (The male version) from contacting them.
It's not 'one big community of men and women that are ostracized' it's 'Ostracized men' and 'ostracized women' and both of those groups are antagonistic towards each other as well the world at large. (NORMIES REEEEE)
