Ok, ok, I REALLY gotta know what Trump supporters are actually offended by being called out as racists. Like, that's literally 50% of their entire thing with the other 50% being homophobes.
Its because they see racism as an identity or ideology not as an action or an observational thing. I see it with my grandmother who will say some notably racist shit but doesnt see it as racist. They dont like the implication of being seen as a racist because they dont see themselves as racist.
Because it's all dog whistles so "you can't prove it! I just don't like DEI, it's unfair!" "I don't like gay people being forced down my throat in all media!"
There's always a somewhat "proper" argument that hides the real reason they agree with it.
It'd be funny to keep playing dumb about what they mean about "DEI" and why they are so grrrr mad about it until they get so apoplectic that they go full nCLANGer mode like Blazing Saddles guy.
