Make your purchases count politically?

The gays are doing similar things to the religious conservatives in coming up with a list of companies which they feel are supportive of their cause. The Human Rights Campaign has come up with a list of companies and their scores on their support list. At some point in your holiday purchase decisions you might consider reading up on companies which are helping the cause of equality and avoid those that are unsupportive: http://www.hrc.org/buyersguide/buyersguide.htm.
Don't want to read the whole thing? Here's the companies to avoid at all costs: Circuit City, Rite Aid, Heinz, Nestle, Rubbermaid, Bayer, Maytag, Nissan, Emerson, Autozone, Exxon, AIG, Franklin Templeton.

Oh, I was wrong about Haagen Daz: it's owned by Pillsbury and General Mills and gets the highest (100) rating.
