Well my friend, I don't have too much of a bone to pick this time :P I do not think relativism is necessarily indefensible, but I find it absolutely a contemptible intellectual position. To say that I am a Christian because I am not a relativist would probably not be far off the mark.

And anyway I hope that most people don't think that tolerance means all ideas are equally valid and true - that would be a disaster. But I am hopeful that most people in fact resonate with belief in transcendent Truth.
