Herp derp I found some stats, but I do not understand them. -CMDR_INTERNET
So you take some subreddits for computer games, sports or cars, interests dominated by males, and then you are surprised their subreddits are too?
A slightly more correct statement would be that females avoid Dota2, NBA and cars. But that is a dumb statement too.
It is not like a woman check out NBA, enjoy it, but then remembers, "Oh wait, I am a woman, I better avoid this". Likewise women do not go to Reddit, but then remember they should avoid it because they are women.
A homepage (or an hobby) having more of one gender does not have to mean that the other gender avoids it. It could simply attract the other sex more.
