You sir are correct. As an urban school teacher I hear from my younger colleagues constantly how oppressive white society is, and how many mistakes we have made along the way...they actually believe this and feel guilty about it. I am in disbelief, and when I present the facts they act as if I’m a monster.
Presenting reality to leftist school teachers is not a good career move, even if you have tenure.
But if you really want to explode some heads, mention the Minnesota Transracial Adoption Study. Black babies, adopted by white middle class families, growing up going to good schools. At 17, their IQ scores averaged 89, about the same as black average.
