I'm with you so far.
Apparently, this is how part of the gay community wants to present itself, just as part of the Christian community wants to present itself as the Westboro Baptist Church does. Why are you making the mistake of generalizing here? This was one group and one incident. It wasn't right, but it also isn't indicative of the entire movement. Also, it's for another thread, but that commercial was pretty dead-on. If you found it revolting, then you should find the church's actions revolting.
Yes, because this one incident is enough for you not to support equal rights, huh? So, because one small group goes about it the wrong way, you feel you're justified in not supporting the entire group's bid for equal rights? That seems petty to me.
