If they can get you ostracized socially (fired from a job, blacklisted in an industry), that is not a small punishment.

Plus, what interests me is the underlying mentality. It seems to be similar. It only does not have enough power right now, fortunately.

But the idea of destroying the heretic in maximal possible extent seems to be a fairly consistent common denominator. It is actually useful to know that it is still present in contemporary population; it means that if enough things go wrong and that faction gains power, you will see similar results once again.
