Was AIDS a biological weapon to exterminate gays and blacks?

Today I read an article from CNN about 'Scientists trace AIDS virus origin to 100 years ago'. That report originates from New York. One paragraph caught my eye.

"Scientists say HIV descended from a chimpanzee virus that jumped to humans in Africa, probably when people butchered chimps. Many individuals were probably infected that way, but so few other people caught the virus that it failed to get a lasting foothold, researchers say."

I wonder how do those scientists know details right down to the exact. If it is a mere guess, it does seems to swing it in favour of anyone but blacks. I'm always a fan conspiracy theories. Not that i think it represents the truth, but it always offers an unique angle to look at how things could had been deliberately 'messed up' and most often than not, there are substantial reasons. I'm not sure those reasons are enough to justify anything but at least it would be enough for anyone who believe that some other agendas hidden beneath the reality is a possibility.

Since the 90s, I had read reports about Aids being manmade, or Aids is a biological weapon created to exterminate a group or a race. A genocide. It was reported that AIDS erupted in America in the 70s after a government-sponsored hepatitis B vaccine experiment using gay men as guinea pigs took place. The widely acceped theory is AIDS originated from monkey that had a virus that 'jumped' to human in 'Africa'.

But it is also true that first few cases of AIDS were already present in America in the 70s before an epidemic broke out in Africa in the 80s. But researchers who believed that it was a man-made disease had substantial proof in that an exercise took place in America in the 70s with the slogan 'Government Interest In Gay Health' and took in large numbers of gay men who donated their blood.

Another interesting fact is that black people have the CCR5 delta 2 positive gene which mean that thee are hundreds of times more likely to contract HIV than any white people. Then there is also the rumors that the American government allocated $100 million of their funds in the 70s to develop a 'synthetic biological agent' to 'deplete the immune system' and it is believed to on the US House Resolution 15090 page 193.

And perhaps the most interesting fact of all rumors is that there is a cure they don’t want you to know about. Search for US patent number 5676977 at uspto.gov (the US Patent and Trademark Organization website).
