a lot more class than most atheists in your position, many of whom tend to denigrate all believers in any deity as moronic fools.
Gee, I hope that most of us wouldn't fall into this. The problem is that here you are seeing the reaction to a small subset of believers. They could be called the "extremists" of believers and do tend to bring out some more extreme reactions.
That said, I will admit that a significant number of atheists are not just un believers but are militantly anti belief too. Myself I think I tend to vary depending on who I am talking too.
I just spent a pleasant day visiting a couple of old friends who are believers (she is a minister, in fact) and part of the discussion was about religious issues. We get along famously.
I have also had discussions with others who I don't get along with so very well.
