"Diversity" is a convenient cover story.
We watched over the past years as "progressives" subjected black and Hispanic Republican high court nominees to a vicious shitstorm that is, even now, nearly unbelievable.
The Democratic definition of "diversity" is "somebody of another color or heritage that hews tightly to a narrow range of leftist ideas." If you look at a crowd of "diverse" people at a Democratic gathering, the actual intellectual diversity is almost nil.
