"So why does that make me 'mindless' or 'arrogant' (and, presumably, make a non-believer the opposite of those two things)?

Please enlighten me. "

I'm not implying that it does - I was at pains to make clear that I was speaking purely from personal experience of certain individuals and not generalising. I respect that many believers have made a considered and conscious decision about what they believe and would ask that, in turn, they respect that my beliefs are similarly arrived at and as deeply held. Therefore, please do not try to convert me to your beliefs and will do the same. It is not belief that I am against - it's evangelism.
