There is vastly more generic similarity than difference... racism is never about genetics, it's always about shared (or not) culture.

The genetic arguement is completely bogus, shouldn't you be removing all the dogs first before you start splitting difference between humans?

It's almost as if the basis of racism is completely arbitrary and unfounded!

To steelman your argument, you should be talking about some kind of `cultural distance'.

Still, doesn't make too much sense.
