My preferred way to browse here is using All and blocking communities I don't want to see. That way I get exposed to new things I wouldn't seek out on my own (for example: British archaeology)
I accidentally blocked a community while trying to block a user and when I went to unblock it, I saw I had 1250 communities filtered. If I had to guess, 90% are either porn, sports, or anime.
My point is that lots and lots of us didn't really love that kind of stuff at the time. It's just that those kinds of jokes stand out, along with race jokes, because they've aged so badly.
