Sadly, a lot of the QAnon types tried to co-opt the Libertarian party in the US due to being disassociated from the GOP. But those QAnon incels couldn't be anymore non-Libertarian.
Libertarians used to be made up of people who supported bodily autonomy, legalization of various drugs, reduced government powers, etc. But have lately been infiltrated by outcasted Republicans.
That's what those on the Left would have you believe. Since anything remotely outside their party's status quo is ignorantly called right wing. But there are multiple iterations of Libertarianism, which themselves fall within a left/right dichotomy. For example, there is Libertarian Socialism, who's values pull largely from the Left. Then you have the more right-leaning Anarcho Capitalist. But what these varying flavors of Libertarianism have in common is mostly all are anti-state and centrist.
The entire purpose of Nostr is about true censorship resistance and speech autonomy. That doesn't exist with AP. Even if you self host, others can block your instance and no one will think twice about why the server is on the list.
Nostr gives you more granular control. You can block the nazis or anyone else. There are projects in the works building the equivalent of a Fediblock if you want to take it that far.
