It's kind of a cringe worthy thread title to be on a Baptist Message Board as well. I can't believe this one is allowed to fly. Well, yes I can actually.
Reread the OP. RD2 was actually arguing that he's met Muslims that denounce radical Islam. And he implied that he was disappointed that Americans would possibly think that the only good Muslim is a dead Muslim. (Actually, true to his usual posting technique, his thread title is different than the body of his post. In his post he asked if America's mindset is, "the only good American Muslim a dead American Muslim?")
But, yeah, the thread title is unfortunate.
