Sure, I guess. They originally got popular in Scotland and the americas for different reasons; Scotland because wearing a woolen blanket is nice and warm even when it’s wet and cold. The slit allows you to throw one side over your opposite shoulder, turning it into a sort of scarf. Or if you need it out of the way, throwing both sides over your shoulders quickly turns it into a cape. You could use a brooch to keep it in place if it’s windy, but that’s largely optional:
They were popular in parts of the americas for the exact opposite reason: Made out of thinner material, they’re great for keeping the sun and dust off of you. They’re basically a poncho, and after a long day of cattle driving or working on your farm, you can roll it up and use it as a pillow for your bedroll, or as a blanket.

Yeah, the sad reality is that creatives often refuse to take their meds. They enjoy the creativity that goes along with their mania, and they feel like the meds kill their creative spark. I can almost guarantee he has been medicated in the past, but now refuses to take any meds because he enjoys being manic.
And being manic isn’t simply being happy and elated… It’s in the same category as schizophrenia, because it causes delusions and breaks with reality. And good luck reasoning with someone when they’re delusional; You can’t reason people out of a mindset that they didn’t reason themselves into.
The dude needs serious help, but he’s still a shit-licking Nazi. His decision to refuse meds is an active choice that he makes every day, and conflating his mental illness with naziism is an insult to everyone who does take their meds and is a well-adjusted member of society.
