People who tell a lot of fibs tend to get a reputation as liars. This isn't magic. There's no fancy latin name for the error of giving known liars the benefit of the doubt, but there should be.

I think crēdulus fits.

Hmm. Good word, and close. But (at least in my English understanding) it doesn't include the ignorance of past action.

A boy who trades the family cow to a wandering peddler for magic beans is credulous. But a boy who buys the magic beans a 10th time from the the same scamp who is broadly known to also sell sawdust flour and moldy bread is an extra level of foolishness.

Extending Musk the benefit of the doubt required that one willfully ignore his history of deceit. That was (and is) an error. Cf. Rumsfeld and Iraq.

Predicting future actions based on past behavior is not some kind of magic, nor is it guesswork. People didn't throw a chip on black and spin the roulette wheel -- they made a very reasonable assumption and ended up correct. Whether there was hate involved or not is irrelevant.

After the "pedo guy" incident, Musk made it pretty clear he's thin skinned, petty and vindictive as well as pretty immature. Based on the public evidence it's hard not to predict these outcomes.

Conservatives all claim to be about free speech but when we look at any of their social networks like parler, they actively censor views they don’t agree with. On social networks they don’t control, they sue parody accounts to shut them down.

Please don't paint with such a broad brush. It's inaccurate, and unhelpful to the conversation.

Provide counter examples.

In global scale, Conservatism is broader term then what one party of 2-party system represents at this moment.
