Well, for starters, the author's baseline claim that there was no factual basis for redlining, which he freely admits is the minority opinion in the matter.
More importantly, the claim that the government and the liberals hounded banks into offering subprime loans, and that it wasn't just the dollar signs in their eyes that made them do it.
These things may be true or may not, but I would like to see better evidence before I simply accept them as facts.
