You are when you could possibly poison people Mr. Cain.
There was a study in NYC for Gay Men who belived they were were HIV/AIDS negative. I recall 500-1000 subjects volunteered. 75% of them were positive and didn't know it. The impetus for the study was the resurgence of "unsafe" sex in the gay community. Mr. Cain, blood is a valuable asset in lifesaving. Intentionaly delaying that life saving by 75% should be a crime.
