Lol, nice strawman you built there. There's no need to "wait your turn for justice". Just get yourself a group who enjoys that kind of campaign and you're good to go! This isn't a "We can't fight for gay rights right now. They just blew up the twin towers" scenario.
In fact, you're arguing exactly like the people on the opposite side: "How dare you care about gay rights. We need thoughts and prayers for the 9/11 victims right now and everyone who doesn't focus entirely on thoughts and prayers is a terrorist supporter!" That's your argument right there!
