Giving blood

There is a shortage of blood donors. Yet, still, gay men are arbitrarily stopped from giving blood. There doesn't seem to be any logical reason for this. All blood is sensitively screened, and it is clear that 'behaviour' is not actually the criteria as questions about sexual activity are not asked of heterosexuals - or gay men, for that matter.

The ban is being challenged in Scotland. I hope it is removed.
