I don’t quite agree on the principle. Maybe Eich isn’t beyond the pale but I think there are very few people who can’t think of ANY a belief someone would have where they wouldn’t be willing to associate with them (say, neo-Nazism or advocating for a return of chattel slavery). I don’t think this is necessarily contradictory with the notion of being “tolerant” since some of these views would essentially make other forms of tolerance impossible if they were adapted by a majority. “I’m equally tolerant of minorities and people who believe those same minorities should be enslaved” seems like a muddled and nonsensical position.
