"There are no meaningful differences" lol. Anything humans find meaningful is meaningful. And humans have always found racial and ethnic differences among themselves meaningful.
Acknowledging that race obviously exists and there are differences between them isn't an obsession. On the contrary, there are only political reasons to deny something so self-evident.
It's amazing that one can convince themselves that the differences between these groups are just skin deep lol. Race isn't comparable to height. Short and tall people didn't evolve under different selective pressures for tens of thousands of years.
in your beautiful rainbow of colors where does yellow end and orange begin? See? Colors aren't real or meaningful. Stop obsessing over color differences weirdo.
