Thanks for data!

Only vaguely relatedly: if you have pointers to (or are willing to synthesize) a reliable calculation of expected lives-saved/deaths-caused by maintaining or discarding the existing Red Cross policies about who is "allowed" to donate blood, especially the relatively controversial ban on male donors with homosexual acts in their sexual history, I would be interested.

Full disclosure: I do have a personal/emotional stake in this question, but I really really don't want to set off a political/ethical conversation about it. I'm asking it here because, as with a lot of politically charged topics, the arguments I've found on both sides are mostly a case of framing the question so as to give the answer one wants to give, rather than so as to answer the question that was asked, and I'm looking for a more objective analysis.

I also wanted to ask this question.

Giving blood is important to me. It is so important that I have chosen not to pursue relationships with other men in order than I can continue to give blood without lying to do so. I expect that sooner or later, I will choose otherwise, and a sexual relationship will be important enough to me to sacrifice my ability to ever give blood again, and this distresses me.

I can accept that the risks of HIV may be high enough to make this a reasonable choice on the part of United Blood Services / Red Cross. However, I would like to be quite sure that this is the case, or to be told that my blood isn't as important as I previously though it was. I was previously giving blood on the impression that each donation saves around a twentieth of a life; this thread doesn't change that estimate enough for me to feel like I can stop donating in good conscience.

I believe you can make an easier calculation: change the denominator from lives to units of blood. How much effort/money/social capital would it take you to convince one more person to donate one more unit? [ignore the cost to that person, as it's likely zero or slightly beneficial]. Calculate the effort it therefore would take you to replace yourself as a donor while keeping the blood supply constant; this should serve as an upper bound for the self-sacrifice you should make in terms of sexual restraint.

You make an excellent point. I clarified that the sexual restraint required is not as great as it may seem, but convincing other people to donate regularly (I have done so at least twice in my life) is still much less of a sacrifice.
