Preferential treatment based on immutable characteristics. It's called discrimination.
Great idea!
What you're engaging in is transparent and glaringly obvious. It's subversive and downright malicious.
Even in a cohesive and homogenous society, you are desperately looking for any and all means to split, fracture and divvy up the population in warring "diversity" groups that are constantly at odds with each other. There has to be something you can use right?
Young children, the elderly, women, atheists or religious folk aren't a diversity group. They are just people.
I know exactly what you're doing, and it doesn't work in cohesive functional societies. They reject it.
