I've often wondered, why is it harder to muster outrage over those?
Best I can figure, racism has more salience when you are magnifying harms to historically marginalized groups.
Not saying it's ever noble, but situations vary, so impacts vary.
It's because the context is always "these characters are stupid" not "people like these characters are stupid."
And thinking about it more, I think the key difference is they have a name. That alone makes them a unique person. It's not "black guys do this, white guys do that" or even "an Irishman walks into a bar." Giving them a name means you can distance yourself from them and not feel offended that Sven is stupid, whereas if it was "A dumb Swede" you'd be offended.
I could see someone endorsing the view that racism is always wrong and yet still worse in some situations. Like, stealing a loaf of bread from a baker is wrong, but stealing a loaf of bread from a starving family is especially cruel.
I'm not an expert here or anything. I don't want to come off like I have it all figured out, I don't.
