Before my two asides, allow me to respond to the OP and the main point: This is ridiculous. Surely our technologies are such that the blood can be carefully screened, regardless of who it’s taken from. :::sniff sniff::: Yep, this reeks of discrimination.
Aside #1: Not that this has any real bearing on the validity of the discrimination, but the topic was brought up…A recent Discovery Channel program studied the sexual habits of men and women, both straight and homosexual. It was curious; regardless of orientation, each gender remained true to the typical sexual behaviors of that sex. Lesbians are more typically picky, less promiscuous, and more likely to be in a long-term relationship. Gay men, however, are more typically open to one night stands, and more open to sex anytime, anywhere, with anyone. Certainly there are one-night-stand-liking lesbians, and gay men who are one-man-men, but the study showed there are certain behaviors more common in one than the other. The same holds true with heterosexuals: men are more likely to be very open to sex anytime, anywhere, with anyone, and women are more likely to be interested in Relationship. (A funny experiment they did: numerous attractive women approached various men in a bar and said something to this effect: “I’ve been watching you tonight, and I find you attractive. Would you like to have sex?” Something like 60-75% said YES. Switch the experiment–men approaching women in the same fashion–and not only did less than 10% say yes, several of the subject men got slapped!)
Aside #2 I can’t donate blood, not due to disease, but low blood pressure. I’ve always been on the low end of the scale, just on this side of safe, but when I donated for my dad’s surgery, it was a big mess. I remember reading a magazine near the end of the donating period, a nurse apparently alarmed by my color asking me if I was alright, and that when I looked up from the magazine, everything went white and sparkly. Vomitting, blacking out, etc. is what followed for the next hour or so, and for at least a half hour, my blood pressure dipped so low they couldn’t get a reading. I was needing to use the restroom, and they wouldn’t let me until they had some sort of blood pressure reading–I would’ve blacked out again had I stood up. Over and over again, the head nurse said, “I strongly recommend you do not donate blood again.” Dammit. Stupid body.
Those asides aside, this archaic law needs modernization. Sheesh.
