Even if other lives don't seem to matter to you, I do care about people, even irresponsible people. Also, we have to pay for it. It does affect you even if you don't get it. Obamacare makes it so gay men can't be charged an increased premium for the dangerous lifestyle a lot of them live. So that cost is spread onto others.
And don't forget that once one of these youngsters (an escalating rate of older infected men insisting on "barebacking" young meat) get HIV, they statistically become indigent. That means taxpayers (you and I) pick up their $500,000 health bill for each one typical by the time they take their last breath with AIDS. As the numbers of HIV escalate, taxpayers will no longer be able to bear this burden for a degenerate lifestyle. It is heroics and fancy medicines to artificially prolong their lives (so they can go out and infect more like themselves) that will be seen as the problem. At that point, the government might start introducing placebos to "thin the burden". My guess is that this product will be urged upon doctors, unknowing, as "the best medicine for patients who present with more promiscuous gay lifestyles". ie: women and children and straight men will get "the good stuff" while rampant gays get the placebo.
At the rate they're going with HIV escalating and their flippant attitudes about being safe (what man with insatiable depraved sexuality curbs his appetite in the moment?), this Machiavellian "solution" might actually become a bottom-line adjustment. I've heard of worse things from the powers that be..
