Racism generally does ignore class. One of my best friends is a very successful man who happens to be black - and large, and very dark-skinned. He's a doctor and hospital administrator with strong financial expertise, definitely a one-percenter. How safe do you think he is if he gets pulled over by the cops? If he's walking down the street toward a white person, do you think they get that twinge of fear, or do they think "Actually, he probably makes about ten times what I do, so why would I be afraid he'd mug me?"
>It is when it ignores class and takes people of different ethnic and economic groups and treats them as homogeneous based on skin color alone.
You mean just like a racist society does (which makes the statement even more accurate)?
Because even a "rich/european/etc" black person is still a n... when it comes to a racist society, and while his experiences might be better, they'd still be shaped by racism.
Class isn't immediately visible. Skin is.
