Fascism itself was also very modernist in many ways, such as the obsession with industry and technology, the aspiration to innovate "beyond" liberalism and Marxism, and even the artistic and architectural styles it adopted.

Another heuristic: Look out for people who would "argue" purely from resemblances. (And primarily by tarring.)

I'm not out to marginalize academia in general. My wife is a former college professor, and a Stanford PhD. However, I would like to call out those in academia who would marginalize others in academia purely for their opinions. If anything, the threat to academic freedom is even more potent, when it comes from within.
