Conservatism is a political marriage of fascists who were never denazified with religious fundamentalists, imperialists/neocons, some of the lumpenproletariat, petty bourgeois, and the actual bourgeois
They are usually all on board with fascism though, so maybe my characterization is flawed
I think it's worth making the distinction. They appeal to different people with different rhetoric that needs to be combated different ways. The divisions within the conservative blob help understand the actions of the whole.
People actively trying to kill minorities / start wars / impose religious law should all be fed into a woodchipper, of course. But it's not like fascist is a synonym with "should be fed into a woodchipper," it's a subset.
