I think it's easy to get caught up in our particular corner of LJ fandom, but fandom, as a whole, is much wider. I wouldn't ever assume that people in fandom-whole would know the social justice lingo.

Is it being too optimistic to think there's at least a critical mass of us, though? Where if someone's around LJ or a couple of the boards, they're at least reasonably likely to be exposed to these criticisms, and will have a much easier time finding out the basics.
