It’s “special” for the very reason I stated.
The essence of “liberalism” is the removal (at others’ expense) of consequences for behavior, especially sexual behavior. In fact the ONLY individual freedom that the left supports is the freedom to rub your jubblies wherever you damn well please with no consequences.
AIDS has no cure, and therefore, has no way to make others pay to alleviate the consequences. They ARE trying, though, through, as you say, an inordinate amount of tax payer funded research into a “cure”.
If you're saying that you think the government spends a disproportionate amount of money on AIDS research, that's a reasonable argument and there's evidence to support it and, frankly, I agree with you.
If someone wants to argue that the government has no role in medical research, that's certainly a legitimate principled libertarian position.
Others appear to be arguing that because the biggest factor in transmitting HIV/AIDS in the US is anal sex, followed by shared needles, that there shouldn't be any research into AIDS. That's where I differ.
