Earlier quoted context omitted.
The vast, vast majority of people who disagree with the left are not fascists. The urge to label them fascists and make them seem monstrous and unworthy of engagement is the impulse leads to civil war.
I agree, but I would suggest you use the same logic about labelling anyone in any part of the political spectrum then. Using terms such as "the left" might seem less antagonistic than calling someone a "fascist" yet come across just as harshly when read / heard by someone who hears "the left" preached in the 2 minutes hate of their preferred news source.
edit: At least nobody I've seen yet. People are probably gonna say it (this goes for any "it" as conversation length grows), but I'd expect it to be downvoted.
