One thing I really like about this new Elon is, while he is liberal, he's more real. There are a lot of liberals playing a part - like towing the liberal line. However a lot of ACTUAL liberals in person might be like, shit let's stop abortion or lets stop illegal immigration or lets cheer black people but I don't want everyone on TV to be black (I'm not saying all of them - but real people have actual opinions like that). There's too much focus on hyper liberalism or LEFTism right now and I rather think the word is not unhinged it's REAL. Same REAL that elected Trump.
In the United States there is very little leftism. If you think there is, point to any major party etc that is advocating to dismantle the existing power hierarchy and transfer ownership of the means of production to workers. The most "radical" mainstream advocacy we typically see is around reform, which really isn't radical at all.
It's true that there are pockets of leftist activism here and there, but said activists have very little power or influence. There's no communist bogeyman waiting round the corner to redistribute your wealth (or whatever else it is that people imagine communism to be).
It's important to reiterate that liberal and progressive are not synonyms for leftism. Advocating for social change in and of itself is not leftism. More Black people on TV isn't leftism, and the notion is quite absurd, especially since it's far from true that everyone on TV is Black now.
The reason this is so important IMO is that we can't have productive discussions about social and political issues if we don't understand the basic terms and concepts under discussion.
As to Musk, I don't know what to think. He's certainly made some good business decisions, but he also goes off the deep end on occasion. I don't think calling him liberal really makes much sense. When you're one of the richest people in the world, your world view is undoubtedly much different than that of an average person.
And just in general the labels "liberal" and "conservative" aren't very meaningful, especially in that most people could be considered either depending on which issue you're looking at. And when you look at how people actually live and what they prioritize, the lines become even blurrier.
