Let's break down the statements:

Is there a movement or group often labeled alt-right?

If so, do they use that phrase to label themselves?

Do they tend to have similar beliefs (say for example support police, nearly unlimited free speech rights, smaller govt, lower spending...)?

When these beliefs are not convenient, do they ignore them? (Ignore police and law for Jan 6, use govt to ban speech and books they dislike, increase govt intrusion for things they like, and ignore their own party running up national debt beyond anyone before Trump),?

I'm pretty sure the above facts are not political at all. They are facts. The hypocrisy has pushed a significant number of lifelong conservatives out of the party. It would be a magical progressive that could simply argue so many conservatives to bail out.

> Why do progressives always resort to oblique arguments like this?

None of this has anything to do with whether Elon is supposedly making alt-right OpenAI, or whether Elon is himself alt-right. The only thing you've accomplished is to reveal that you don't know what "alt-right" means.
