Actual fascism would eliminate the radical left, the anarchists, the terrorists, and the filth and vermin who comprise its illiterate and disaffected demographics, which might be one of the few redeeming qualities of fascism, akin to how Mussolini went after the mafia.
Even a broken clock can be right twice a day.
Assuming a short fascist coup in American and Britain resulted in most of the radical, degenerate, anarchist left being rounded up, publicly executed without trial, and made an example of on social media for the rest of the world to see, and for generations to come, I would be tempted to support such a thing, much as it would be a nice cleansing of surplus and worthless population.
Hopefully the idiots will put their archaic racism and sexism aside, and merely focus on the worthlessness of the radical, anarchist, degenerate left - something which I'd venture all thinking men and women of some margin of decency and character could agree to, not being a simple "left/right" issue but more of a human and common sense one - then we could have a sort of cultural cleansing of sorts which pretty much all well-adjusted normal people regardless of their politics could shake hands on, and easily turn a blind eye to, as well as silly leftist notions of "freez peach", "muh rights", "censorship, derp derp", which their cultural and moral superiors can quaintly ignore in theory and practice, like the whining of a helpless, dependent petulant child, or the squawking of a feral ape or dog, nothing more, perhaps even less.
