My point was that if your goal is to end racial discrimination, free-market forces left to themselves are not sufficient. Your point - or at least the argument you justify it with - doesn't really make any sense. Lets consider a result of the same argument applied somewhere different: "...a significant number of people were environmentalists, and strongly favor clean air. If you opened a factory that polluted or purchased supplies from one, your customers would disappear. If your bank made loans to polluters who wanted to finance new machinery, your depositors would take their business elsewhere." Suddenly your mechanism for enforcing racism seems implausible, right? After all, if it worked, virtually every popular left wing economic regulation would be superfluous.
