I joined a Christian forum and was banned after only two posts and the reason given was that I had engaged in an out and out attack on their belief. Not true but I know why. It was because I stated that ideas are there to be taken apart and without favour to anyone or anything. That must have been it. Either that or referencing the age of the Earth and the Universe. But nowhere did I actually attack Christianity itself. I joined another site and that was alright save the page subsequently became cached so now I just stick to the five sites you see in my signature. We get some Christians over at rat skep but they come unstuck when we attack the idea though never the individual. I actually think atheist sites are better because we have only one thing in common whereas theist sites all have an entire belief system so there is not much scope for good debate. Now I would say that given how I am an atheist but actually it happens to be true as well.
A MIND IS LIKE A PARACHUTE : IT DOES NOT WORK UNLESS IT IS OPEN
