Do you not think the black people have not been victims of some of their own life choices?   I know Bill Cosby is currently persona non grata to the world, but in  the past he had some things to say that the black community should be taking to heart.   Statements along the lines of "If you do not want to be taken for an idiot, do not act like an idiot."
Now let us start on that 400 year history.   You blame whites for slavery.  Did you know that it was other Africans that rounded up Africans to be sold into slavery?   Did you know that they have practiced slavery for centuries in Africa?    Did you know blacks owned blacks in this country and that some of the slave owning blacks were worse owners than the whites?    I am not going to say the vast majority of white slave owners were saints, because they were not, but to put it all on whites is an absolute falsehood.   I bet none of this is in the new museum.  Too many people don't want it known.
