Lenin, Stalin, Hitler, Mussolini, Moa, Pol Pot, the most murderous leaders of all time (by a factor of what, 100 X???) were all atheists, correct?
Since we have a democracy(representative republic actually) we change our leadership often enough to slow the debates and conflicts and give time for compromises.
Religions, on the other hand are more stagnent and prone to collecting power at the top and not changing. This is evident by the backlash of churches in the protestant religion (for example) who are severing their ties with the mother churches because of disagreements with the political views of the leaders of such churches.(hit them where it hurts, in the wallet)
That is what propted me to post on this thread, since it is a sore spot with me. (I digress) Now that I have totally lost my train of thought, I will quit! :-)
