Other atheists, a bit of a concern?

My disdain for self-delusion is not limited to Christians, they simply outnumber all the various other religions and cults in my vicinity and particularly here in R&S, so they receive most of the guff. Parenthetically, and possibly because they don't have the numbers and power to get away with it, most of those other religions and cults are not as arrogant, supercilious, pedantic or shrill as the aforementioned dominant one.
