I don’t think there’s an all-encompassing term for people who have “destructive”/harmful beliefs considered conservative. Most I can think of is “bigoted capitalists”, but even “bigoted” could be interpreted way differently. Plus, that excludes bigoted non-capitalists so it has a more narrow usage…

What I go with, though, is “fascists” and “collaborators”. Plain and simple, straight to the point, but most importantly no chance of confusion – that’s how I see our conservatives, their supporters, and their enablers. Ultra-socially-regressives (usually religious) who want a system that enforces/maintains a social hierarchy they deem “natural” (or having a religious justification for the hierarchy). Maybe “wannabe fascists” or “social fascists” would be more accurate, since generally people think of a dictatorship when they think of “fascism”.

“Oppressors” may also work, and it also can pair with “collaborators”. It’s more general, but I think here the flexibility may come be an advantage, and it isn’t tied to a specific set of political beliefs, it vaguely just means “those who use unjust force/threats of force to control others”. Of course, contemporary conservatives follow this definition.
