Well, if you had heard the things Elon says, seen the people he signal boosts, or heard of the people and groups he associates with, then you would understand why people are accusing him of spouting far right nonsense. It's because the things he says are frequently far right nonsense, the people he signal boosts are frequently people who spout far right nonsense, and the people and groups he associates with are frequently significant sources of far right nonsense. And I'm not a Democrat in any sense other than thinking they're not as bad for the world as Republicans are, but I can think of at least one good reason to throw rocks at "the other color," that being when they're propagating harmful far-right nonsense. I'd have thought this logic would be bulletproof, but I find myself cowed by the counterargument that "I have no idea what you're talking about but you seem mean."

Paying attention to the world around you is a great way to avoid making yourself look silly, if you're interested in stopping it from happening again.
