Powerline cites Michael Fumento's powerful and contra-PC stance against excessive AIDS funding. Domestically, Fumento's argument that AIDS research receives an egregiously disproportionate share of public funding is undeniable - and his corollary thesis that this imbalance was founded and is perpetrated upon a series of lies and misinformation is damning of the AIDS lobby (particularly when one fully recognizes that the cost is literally a matter of life and death for those needlessly dying of unfunded diseases for which cures might otherwise have been discovered).
All of this is basically irrefutable in America. Research funds are finite, and should be used to the greatest benefit of the greatest number of people - particularly targeting diseases which cannot otherwise be prevented. Regardless of liberal stammering, AIDS can be fully prevented through responsible personal behavior - as the link notes, heterosexual men are more likely to contract breast cancer than AIDS. AIDS research is overfunded, and so cancer, Alzheimer's and Parkinson's (among other afflictions far more deadly than AIDS) are underfunded.
My only observation would be that AIDS is a far graver matter overseas - particularly in sub-Saharan Africa, where infection rates may exceed 1/3 of the adult population. Yet generally unpreventable illnesses such as respiratory infections, diarrheal diseases and malaria are just as prevalent - and cancer, heart disease and other "common" causes of death are just as prevalent overseas as in the U.S. Thus, there is a greater global rationale for AIDS research than exists in the U.S., yet even those areas would profit more abundantly from a reallocation of some funds away from AIDS.
But medicine is money, and money is politics. The AIDS lobby - intimately associated with the homosexual lobby, for quite understandable reasons - has dominated the political game and confiscated an incredible amount of money for their efforts. I sympathize with their compassionate self-interest, but research funds should be allocated by need and promise of progress - political correctness and unethical lobbying tactics result in increased deaths, both here and abroad.
