Do you mean banks were not investing in areas that had a history of defaulting on loans? You do understand the definition of the word "history", don't you?
So, please tell us why you make the association between racial discrimination and the history of bad lonas in the areas you claim were being racially discriminated against.
In short, why did the areas banks didn't want to invest in have a history of bad loans? What was the relationship to race?
... I'll wait for your answer on this one.
Please do not hold your breath waiting for an answer from "real dumb" He will change the subject.
