While I disagree with everything the church group "God Hate Fags" (GHF) does, I think we forget one basic thing in a discussion like this. They have the same right to free speech as anyone else. I was taught in school that the motto of this country concerning free speech was "I might not agree with what you say, but I will defend to the death your right to say it!" And, as a Vietnam Veteran, I have earned the right to that opinion.
A group like the "GHF" would best be ignored and when they lose the public eye will fade away into a bad memory.
