In one sense, it's biased towards people who have sex with men. In another way, it's protecting people. Without stereotyping anyone, I'd assume that there wouldn't be a large number of non-straight people who would be signing up to be a blood donor. With all due respect, the number of straight people still donating probably means that it doesn't change a major amount of blood produced in the long-term.

It's a shame that we can't drag those emos to the blood donor places so that when they 'blood-let', they can give their healthy blood to someone who needs it! (Okay, wishful thinking perhaps).

I'm all for stem cell research. As long as it doesn't turn us all into mutant freaks like in I Am Legend / 28 Days Later / Random Zombie film.

The reason people don't want an "opt-in" scheme is that a lot of people like being in control of their own body, without having to worry about making sure it stays in one piece. There are also the adverse risks which could possibly involve someone dying in an unusual circumstance, only to be revealed later that some mafia boss had scouted him as being the perfect organ donor or something crazy like that... I guess I'm indifferent to it. But I think as you get older, you're more likely to sign up.
