I agree on most parts of your respnse, but I was aiming at precisely at how the commenter I responded to tends to make absolute claims for what, it seems to me, are relative to their position and attempt to instate as more common and common-sense than it really is, and betrays a certain blindness to a simple psychological fact that people usually react more strongly to things that pressure them more (a relative phenomenon) and ascribes to this reaction some political valuation (an absolute).

I myself do not find left-right divide that much useful, at least to describe this melting pot of our time.
