Today, for not complying with a promoted ideology, he'd similarly be banned/censored/cancelled.

Ironically, however, the currently promoted ideology is one that forces (as the only acceptable ones) views that are even more extreme than Hirschfeld's.

So if anyone today dares refer to sexual deviations (from typical/'normal' heterosexual practices) as 'deviant' (which, according to definition, they, simply, are), or as 'perversions', which they also are, again by definition, workeist neo-inquisitions will gag/ban them, preventing their 'hateful'(!?) words from being read by others, even by those who want to read them.

Book burnings are more symbolic than effective. Today's insidious 'wokequisitions' apply 'shadow'-bans, etc., on whole authors in general, not just some specific book of theirs. That's more effective than symbolic, and thus even more harmful to the free flow of ideas.
