the reason the policy seems homophobic is that it came about during AIDs hysteria when people thought it was a gay disease and the policy does not include those who engage in risky sex outside of gay people AND they test the blood anyway AND you can't even get an exemption if you have recently tested negative and not engaged in sexual activity with new partners since then.
essentially it is "its just easier to ban gay people than be fair because who cares"
not sure how it is hard to understand how that might tick off some people. not really an issue that matters to me though because I can't even give blood anyway because of medication.
