I'd say it is in the end an ethics issue. Sure, the tone may be offputting, but... I think there is value in having people around who actually hold beliefs and aren't as quickly willing to put their beliefs aside. Society as a whole benefits from a corrective to ultra-progressives - even if what the progressives want is a good thing (which, to be clear, it almost always is!), move too fast and you end up losing the masses along the way.

I don't know about you, but people who hyperbolically label stuff "evil" without providing justification seems like exactly the type of person who would flip-flop depending on whether it's politically expedient for them or not (eg. preaching fiscal responsibility when the opposition is in power, but then being fiscally profligate when they're in power).
