"The problem is that if you are, say, at work and they do a blood drive and you say "I can't. Sorry." that potentially outs you to your coworkers that you are gay or have some other issue that disqualifies your blood."

I never heard about that as a concern, and I have to dismiss that as silly, given the many reasons why you can be disqualified. I mean, you could just have low iron or some other minor health issue.

What I was alluding to is that some people feel it is not acceptable or just to have a blanket exclusion of men who have sex with men. I can't imagine that your answers to the questionaire are allowed to be shared with anyone though.

I've never heard of anyone being offended by the exclusion of people who have spent time in Africa or Europe though.
