It should be also mentioned that HN leans left, so when similar left-wing scare phrases, such as comparing Trump/GOP to Nazis comes up, or similar "the opposition are fools" topics such as anti-mask/vax, global-warming etc; It's seen as correct and acceptable.

It's the same kind of thing as right-wingers acting hostile to any negativity towards police/military, even if criticism is valid. Criticise lenient policies in cities with vagrancy problems, and it's touching a nerve.
