He legitimately had his brain damaged during his induced coma. This isn't like making an ableist joke either, I'm being 100% serious. He was somewhat always angry (for no reason) would cry and stuff inappropriately before, but ever since he almost died he's been so fucking pissed constantly. No off button, no "deep thinking", just yelling, screaming, etc.
He went from anti-trans grifter "professor man" hiding under the guise of "I just want men to be men" (while crying and sounding like Kermit, but moving on...) to an oil lobbyist, just outright Trump supporter, just all the shit right winger love to push and talk about, he picked it all up. He dropped most of the weird Bible shit that, while weird, was at least somewhat unique to him and now just rants about "fat women not being attractive" or retweeting "cum milking gifs from China" (lmao). He really dropped all pretense of being an academic. Perhaps to appeal to a broader audience, but I think it's because he can't think like he used to. Not claiming he was some super thinker, whatever, before, but he had to be able to perform in a certain way to have his former career, and I don't think he can do that anymore. It's sad in some ways, hilarious in others. He lost whatever ability he had to ramble and make shit up about how Marx didn't clean his room enough and instead he's like "yeah!? Well! Uh! Those studies use, uh, you know, well, you know, the data, the data is bad, and well, the LEFT, the Je-I mean the Bolshev-, the Marxists! are just, well, you know, the women are taking all the jobs and DEI and, well, there you have it! No more oil! It's like, wow! There it is! Bloody obvious, don't you think?"
You can also see the exact same behavior in Fetterman post-stroke (not trying to pretend he was a socialist before, but there is a huge difference in how he acts after the brain damage from the stroke) and Biden as his dementia worsens. Like literally you can see these liberal guys, already various levels of right wing, have major brain injuries of different types, and they start going harder and harder right wing. And it's not subtle either.
I dunno. I'm not gonna claim like "all right wingers suffer from bad brains." I'm simply observing a small group of people and stating what I see as a pattern 🤷♂️
