Well, my ever-cordial newbie FRiend, for starters, 90% of lung cancer cases occur among smokers. Lung cancer is a preventable disease -- just as you're not likely to get HIV if you don't have sex with someone who is HIV+, you're also not likely to get lung cancer if you don't smoke. And if you do still get lung cancer even though you don't smoke (that other 10%), it's probably because you've inhaled asbestos fibers or radon or some other completely avoidable carcinogen.
So yes, lung cancer and HIV/AIDS are both avoidable diseases. So what?
Why should we fund HIV research with tax dollars at a vastly higher rate than lung cancer? Or heart disease? Or diabetes?
Something seems disproportionate here....Why should HIV research get all the money?
Not so with AIDS. Even if it is contracted by a couple of other means other than homosexual sexual behavior, the source of it was still the same, in all cases.
