"......implies gay men are inherently sick....."
Well, duh. And of course it's a low priority to the groups. In order to argue against the ban they would have to deny studies that show the higher disease rates in the gay community. Sure, lets put everyone at greater risk of receiving tainted blood in order to be PC and not thought of as "homophobic". This little battle will be going nowhere folks.
Maybe that is their strategic goal - eliminate the statistic that shows that the population of gay men has the highest infection rate. It is a homophobic statistic and can be used to justify profiling against homosexuals. That does not fit the PC agenda, or the gay rights agenda, therefore must be done away with.
