Conservative doesn't mean they don't want to change things, that's an intentional misconception. Its obvious if you see how much settled precedent they are willing to overturn. Conservatives just believe they deserve power, they think they have the divine right to rule over others and that other people do not have that right.
I used to think that, but these days I think it's basically the No True Scotsman fallacy. When most of the the people who call themselves conservative are fascists, then conservatism is fascism. It wasn't always, but it is now.
Sure they are. It's just what they considered long established and what you consider long established are different. They don't want to go back to the 70s. They want to go back to the Gilded Age. Or Hell a straight-up feudal monarchy.
