One has to wonder if, when he was undergoing his heart replacement surgery, Cheney would have opted for blood donated by a gay man.
Perhaps blood banks can take blood from gay men and have it labeled as such. They could allow the blood recipient the option of using it or not. Oh, and make its acceptance mandatory for Members of Congress and gay activists.
I have been in situations where blood transfusion was necessary. If you have a system of labels I wouldn’t give a tinkers damn as to the integrity of such a system. I believe that there are enough homos in the medical profession that they would mislabel for their own constituency’s benefit. Best is just to not have any tainted blood in the transfusion world.
