America is a diverse country. America has always been a diverse country. Our democracy should reflect our society, not suppress it.
It depends on what the premises are for diversity. Different white European ancestry or different races? It started when alien shapeshifters were allowed in, then the same ones pushed through the 1965 Immigration Law to eliminate western civilization by outbreeding white people in their own country with different races. Same goes for Europe nowadays. The same shapeshifters infiltrated all branches of government over there also.
You are a subvesive idiot trying to push your Cultural Marxist lies.
