It’s not about political disagreement though, it’s about the fundamental rights of people to exist.
The defederation questions are not over disagreements on “how much should we pay in taxes”, it’s “should this group of people be allowed to publicly exist”.
Is it “healthy political discourse” to allow antisemitic propaganda in furtherance of fascism? I’ve noticed the vast majority of “free speech absolutists” belong to groups that are not currently being targeted by hate groups.
