Pretty much everybody, I guess, including the cats (my cats like to look at the monitor when I watch anime, I don't really know why, since they pay no attention to live-action stuff). Heck, I'll even talk about the really lousy ones with my mother, and we'll laugh about how pathetically stupid the show is. My father seems to think it's just creepy or something, though. Talk about reversal of cultural norms, eh?
For that matter, everybody knows I'm a lolicon, too. Again, except maybe my father, who, despite having heard me use the word for the last few years, still doesn't seem to know what I'm talking about (which is REALLY weird, considering my choice of wallpaper slideshow material for my PC should be a dead giveaway).
It's just easier to let people know about everything than waste my time trying to hide it or beat around the bush.
