From the perspective of a pre-abolitionist society, it evidently was, but that's not a political issue you're gonna have to deal with in 2025. Consider yourself lucky.
> Fascism has a very clear definition.
First of all, that isn't true. Secondly, even if it was true, it wouldn't matter. You are using the word as a though-terminating cliché. That doesn't work in the long run, you'll just get ignored. As a result, you can pat yourself on the back for calling out fascism while all the behaviors and actions that you believe to be fascist are mainstreamed and affecting people's lives. If I was you, I'd be more worried about criticizing those behaviors and actions on their merits (or lack thereof), rather than trying to tie them to some textbook definition fascism and dismissing them wholesale.
