Sure you could. 23 year olds who like to attend pokemon meetups. University chess club members. Small town attendees of quilting bees. Maker faire regulars.

They're self-associations largely based on personal interests, so it shouldn't be surprising that there are common personality traits within the groups. You miss out if you blanket-judge people based on them, of course, but that doesn't make them invalid.

That's in contrast to race, gender, etc. where the group is not self-selecting.

See, you're wrong though. I attended Pokemon meetups at school while also being a member of a fraternity. I got shit for is but I just didn't really care. I gave people shit for other "weird" stuff they did all the time.

You're also wrong in saying someone who likes Pokemon is a specific kind of person. I know tons of "jocks" who played WoW and Pokemon with they're down time. In other words, your fleeting interests do not, and should not, define who you are.
