Yes, enjoyed your well thought out post.<quoted text> Atheism is not a religion. Some atheists seem to be on the offensive, others may seem to be on the defensive. Others just take it for granted, and try to explain rather than to argue.
I think it may be a matter of personality, as much as viewpoint.
An atheist who is on the offensive is more likely to claim he knows that there is no God, and more likely to be harsher toward believers in general. As an agnostic atheist, I do not believe in a God but I certainly do not make a claim about knowing there isn't or having proof that there isn't. And as one who cares more about ethics, I care much more about the ethical views which are intertwined with one's theological views, than about the theological views themselves.
A kind Christian is and OK person in my view, as long as the kindness is not just personal but also extends to that person's political activities and advocacy - i.e. there are good liberal social and economic justice Catholics in politics whom I like and admire. I also discriminate between a worse and better Pope, for example - former Pope ratty being a horrid person, and Pope John 23rd and the current one being better ones.
Present Pope seems positive so far.
