Back during the Clinton days as governer, Vincent Foster was involved in a scheme that “donated” prisoners blood which made its way to Canada if my memory serves me right. There was a money angle in there somewhere. Some things never change.
New rules for donors were brought in. Gays, injection drug users are still allowed to donate blood — but, they are supposed to check a little box on a confidential form. If the box is checked, the blood isn't used. This allows the high-risk donors to participate in (e.g.) workplace blood drives, and still avoid contamination of the whole blood supply.
Naturally, the gay lobby here is pushing to eliminate the “discriminatory” rules. Better dead than politically incorrect, seems to be the underlying philosophy.
