I do not feel threatened, disturbed or frightened at all. I was an atheist and I enjoy a philosophical debate also.
I didn't come to God through church or the Bible even though that was slightly how I was raised. I briefly studied many religions and there is much in common and the common ground(good and evil) is what caused me to let God in, and the deal was settled once that happened. And I do hope you feel the same way at some point.
I hope we can agree to disagree for now.
