Not all Conservatives! /s
But like, their leaders do most of this and they support their leaders so it's an irrelevant distinction. In the US it's essentially boiled down to the Republican party: The RNC and the party supports Trump who is an obvious fascist, racist, etc. They support him to the point of making their entire policy just him. Whereas normal parties have actual policies and the POTUS is merely the leader of the party. So if you support the Republican party you are de facto supporting Trump and are therefore supporting straight fascism.
In the past you could at least support Republicans for their policies (these have their own problems) but not support their current Presidential candidate/POTUS. But they've gone all-in on Trump so it's a wash.
