There are several topics here that raise people's ire -- things that folks have a "high emotional connectivity" about. Are we to minimize discussion of all of those things, or just the ones that you personally object to, or don't feel add to personal development?
What I mean is, everybody has topics that either don't interest or actively bug us... it's up the individual, I feel, to either ignore or deal with those topics, and ignoring or dealing is part of our particular path in personal development. Our resistance itself is an avenue for growth. For myself, that has included the whole topic of religion, which many might feel the same about as you feel about political discussion.
