I’d think that in the practical sphere it’s irrelevant what a philosopher says as there’s always going to be, say, a sister, which will bend the philosophy to whatever opinion the anti-intellectuals in charge like to hear.
The solution is to have a populace informed enough to not put such people in charge.
As to our own Red Scare over here: Yes the Radikalenerlass also targeted Anarchists but it was abolished before I started shool, or the GDR collapsed. What gets you in trouble nowadays is (as the constitution intended from the start) trying to undermine the free and democratic basic order and I don’t do that. I want to radically expand it, in a Kantean sense my politics are those which make it a natural law, see homeostasis.
