2 cents;
It is my observation from being on 'a few' atheist forums over the years that atheist overwhelmingly treat Christians especially, with far more compassion and generosity of spirit than Christians treat us on their forums. I've tried a few. Never lasted more than an hour or two before being banned. All I did was to ask a few questions. Those people seemed very insecure in their faith.
Having said that, many atheists I've run across do not extend that compassion and generosity of spirit to Muslims. That saddens me, as bigotry tends to do.
Here I post some observations, I'm not after a debate
