Maybe it's time to change the policy to a one-year or five-year deferral instead of a ban. But it should be changed based on actual evidence and data, not based on a completely flawed and mistaken civil rights crusade for blood donors, who simply have no rights.
I think it's quite likely that the lifetime ban on donating for men who have had sex with men is a product of an era before effective (or maybe cost-effective) tests for HIV in donated blood, and when the disease could go decades without being detected.
And I agree with you that there's no such thing as the "right to donate blood", but there is such a thing as a right to equality. If a group of people are going to be banned from donating blood, then there should be a legitimate, scientific justification the ban.
This is also a matter of pragmatism for the blood service: it does them no good to tell a healthy donor that they don't want his (or her) blood.
the problem is that Homosexuals think that if they arnt allowed to do anything they are being discriminated agianst, its silly they need to wake up to the facts and accept that there certian consequences we all face with our sexual orientation, this just happens to be theirs.
Wait one minute. I think that if the ban is based on a real increase in risk associated with certain sexual contact (just as there's a real increase in risk associated with having lived in certain parts of the world), then fine... though at the same time, it's completely valid to ask whether this risk can be adequately addressed by other means besides an across-the-board lifetime ban.
However, if the ban is based on outdated assumptions, or on some general idea that gay men are "unclean", then I think it's right to challenge it.
I'm not entirely sure which is the case here.
