There is a difference between refusing a loan BASED on race, and refusing a loan to a minority.
The community reinvestment act of 1977 is more complicated, and there are some potential concerns here. That being said, the assets resulting from such practices were graded AAA, and sold around the financial world like hotcakes.
I have a specific questions for you Duncan, so stop the dodging and try and give them honest answers:
1) If these assets were as toxic as you describe why were banks trying to buy them from each other, well beyond their legal obligations to any act?
2)Why were they lobbying (successfully) to get their credit limits increased and then buying up more and more of these assets?
The only answer I've found that's consistent with the facts is this one:
Subprime loans were so profitable, that they were aggressively marketed in low-and moderate-income communities, even over the objections and warnings of housing advocacy groups like ACORN.
Which you can find either here:

Even more telling is this:
There's a major factual problem, though: with a single exception, no bank sought CRA credit for its subprime loans. And the investment banks which were purchasing, bundling and securitizing the loans were not covered by CRA.
