I wasn't commentating on the rationale behind the thinking or whether it is right or not, just that the idea of the internal enemy is not owned by any one political persuasion.
Though I'm sure right-wing groups believe themselves to be tolerant of one-another and their allies and others with similar aims, and that groups that oppose them are intolerant and therefore must be met with intolerance. The paradox of the paradox of tolerance is that you can't claim tolerance by excusing your intolerance with the paradox of tolerance. Or said another way, one man's tolerance is another's intolerance.
