Jim: you have completely misunderstood everything I wrote if you think that I believe "we can't know anything for sure".

That being said, one of your generation's greatest flaws, especially among Christians, is the obstinate clinging to cultural norms masquerading as true Christian doctrine. The generation of evangelical Christians older than me have shown an unfortunate lack of humility that has contributed to an even greater misunderstanding and caricature of Christianity in our culture.
