I own stocks of several companies and I definitely hope he stays as far away from them as possible. He is a man-child into alt-right and antivax conspiracy theories, this is toxic to any brand unless you are selling to the MAGA crowd.
The irony is, there are plenty of products and brands that absolutely would like to sell to the MAGA crowd, but you would not expect electric cars to be one of them, especially as their presidential candidate announced that he would ban them.
I really think people should stop saying "alt right" for anyone more conservative than Bernie Sanders. Alt right is an actual thing, and the trick of calling a mild thing an awful thing stopped working a few years ago.
Elon has retweeted things about The Great Replacement and anti-vax conspiracies. He is very much on the alt right, not "slightly right of Bernie Sanders".
Hard to know without citations what that means in practice. And retweets? I don't know. I like every YouTube video I watch regardless of whether I like it, so I know what I've watched.
Things that you could do accidentally with a thumbslip should only have a certain weight attached, and being quick to reach for a description that includes people who want Jewish people dead should be done cautiously.
