Civilized countries, including France, The UK and Japan, have already lifted the ban on homosexual blood donation.For example, tell us why blood banks refuse gay male donors.
Both the AMA and the Red Cross are in favor of lifting here in the US. Alas, due in part to fear mongering gasbags like you, it hasn't happened YET. The short answer is fear, ignorance and stupidity.
I hope you found the TRUTH entertaining!
