I fully support the existence of the NeoGAF transgender sub-community, and I'm glad that many of the members of that sub-community have felt safe enough to reveal themselves and talk about what they've gone through. We'll continue to ban the shit out of you if you go into the pics thread and call Jamie a "trap" and what have you.
But I'm not universally banning the word "tranny" from GAF. People don't know what to call TG people. We're dealing with something that's not really on the radar very much for the general populace. "Tranny" is the main word people know, and it's only because of that that it's used both innocuously and for jokes and insults. If tranny is then relegated to slur status, and the next word becomes the norm, it will be used in the same contexts as tranny and we'll run into the exact same issue as soon as it becomes the popular term. And I'm not going to help perpetuate a fallacious cycle of political correctness.
I think we made major headway when several TG gaffers came out into the open and answered questions and helped educate people a while back. It definitely changed the tone of the OT forum. That's the path to understanding and acceptance, not this white knight championing his cause of the day (clearly only caring about the championing, not the cause).
