I've been kicking this suggestion around for awhile: given the high number of LGBT on this forum, as well as other SJAs, shouldn't the primary focus of FQA be social justice?
Perhaps, but the FQA banner wouldn't make much sense. Frequency Questioned Answers suggests that our purpose would be something along the lines of Snopes, and less in line with social advocacy. We can certainly do both; assuming that transpersons rights are next to be addressed, there are misconceptions that will need to be addressed and corrected. And it's not like sites such as Alternet and Think Progress aren't open about their support for equality, and other similar issues. If anything, such articles would need to be addressed from the appropriate viewpoint.
That's something I'm having to do when I write for GMP. It's a bit of a pain sometimes, but it's doable and, in some cases, helps provide some focus for the topic at hand.
