“ race and ethnicity are social constructs that do not have a basis in genetics.”
This is true enough.
We knew races before genetics.
And races change. Irish and English, for example, were separate races. Or a “black” American may be 80% European. How is that the same race as a South East African?
Of course there are genes associated with traits we use to define race. They are a minute percentage of the total number of genes we have.
Given this, the pc woke liberal cries are still absurd and irrational.
The left define and try to pinpoint and enforce race more than anyone.
To them it’s a surrogate for certain Marxist constructs that can be applied to the US and the world.
Race is not a scientific construct.
Scientifically speaking there is no such thing as race.
