I question the merit of the Christian faith. I question the intellectual honesty of its followers. By that phrase I mean their willingess to ask themselves tough questions. I used to be a Christian and I remember avoiding those questions, by either ignoring science or relying on very weak arguments from Christian authorities, which I should have known to be specious. It was later when I questioned my reasons for wanting to hang on to my faith in the absence of good reason. That was my final gateway to atheism.
