Dr. Gilbert, when we talk about GLBTQ2S health, all we keep hearing over and over again is about stigmatization and discrimination. I want to ask a question about the blood donor ban on men who have sex with men. We know that there was a promise by this government to eliminate the five-year period of abstinence. That's been reduced to one year I understand. I've heard anecdotal testimony from gay men about the impact that has on their self-worth.
I'm going to ask you directly. Is there any valid scientific evidence that justifies enforcing a one-year period of abstinence on men who have sex with men from donating blood?
