I've even seen a moderator on Lemmy describe "freedom of speech" as nothing more than a right wing wolf whistle and banning someone.

A minor point (but maybe English is a second language): what right wingers do is "dog whistle," as in a sound so high-pitched only dogs can hear it. A "wolf whistle" is, funny enough, a kind of non-verbal cat-call. That is, it's a sound expressing interest or approval, specifically its the hi-lo whistle like Phwooooot- WOOooooo.
