I claimed that it's not the sole contributor. I don't think we have laws anymore that target one group over another. There are some that disproportionally impact certain groups, but that's my entire point. You can't look at the end result.
> genetic inferiority
I'm not very interested in genetic differences among groups, because I reject the whole "groups" thing all together. So why would I talk about it? But I guess if you do look at groups, cultural similarities are more obvious than genetic differences. And those are driving most of the differences IMO
> what was the Civil Rights movement about, exactly? What does "Colored" mean in this sign?
Correct, it was equally wrong to group people based on "Colored" back then as it is now. I'll also add that back then there was a lot less immigration so the group made slightly more sense (uniform), but it was still wrong.
