I am also a libertarian socialist and anarchist, but many people confuse it for American libertarianism, which at one time was good, but is now co-opted by QAnon incels and ostracized conservatives. People here will confuse the two and will downvote you hard out of pure ignorance, simply because the word “libertarian” that they’ve seen other misinformed people wrongly lump into the same boat as “bad” or “nazi” and think you’re in the same category.
They were never Republicans. The Republican Party split post-Trump loss and a bunch of them infested the Libertarian party.
