zealot,
fanatic of ANY kind!!, who tries to force upon one; the 'my way or the highway' (or death!) attitude! -foaming at the mouth with their beliefs, a 'non-subscriber's' best
policy is to RUN!!
there simply is NO retaliatory argument for dealing with these types! -they can only 'glom' with their own kind, due to their insanely 'logic' resistant beliefs...
