Same with [members of] simlar religions ...
there's no more bitter enemy of a religios person than a just slighly different one. After all, discussions between religios and non-religous people tend to be short due to lack of a common basis. But between two religous people of just slightly different flavor ... that's where the most heatet debates erupt. Common basis AND desire to differentiate are key ... Same withe techies.. No common basis for dicussions with "normal" people, no argument, no toxic relationships. :-)
