People don't choose to get cancer. AIDS, however, is almost completely voluntary. Nice job, throwing slurs at dissenters, though. That's the way to show tolerance! :)
1) Many people in the west voluntarily choose to engage in behaviors which greatly increase their chances of getting cancer. So, in developed societies, much cancer is voluntary according to your definition. Meanwhile, in Africa, many women have no choice whatsoever about being forced into activities from which they contract AIDS, and their children are certainly not born with it voluntarily.
2) First off, the basic point the "dissenter" made was completely incorrect, there is not so vastly more research effort going to AIDS than there is to cancer and there is no factual basis that would lead one to such a conclusion, it was purely an unfounded assertion. Second off, my supposed "slur" was nothing more than reading what was obvious from the derogatory way he (yes, he, that too is obvious) referred to gays and those who advocate for their causes.
