Ps. playing the devil's advocate is something I would expect (and have seen) in all XNXXs. N is supposed to be about making your own conclusions and when a conversation is one dimensional something starts to itch in me as well.
I think it's only something very fundamental in humans that you will percieve the ways and capabilities of the majority as normative. It doesn't mean you have to put a value in things being normative however. I for one am very happy people come in different flavours.
