All the replies to this question are interesting and thought provoking. I will add my own thoughts to the discussion.
There seems to be different lines of thought on this issue.
Some people believe there is no HIV and no AIDS.
Some people believe that this disease does exist and that it is caused by a virus and some believe it is caused by an environmental pollutant.
The people who believe that the disease exists then debate on how it got here and who did it and why.
I used to work in a medical lab that did HIV and hepatitis screening and I do believe these viruses exist and are transmitted from person to person through certain body fluids and the exchange of sexual body fluid is one of those transmission routes. It does not mean that people who have HIV will indeed pass it to each other through intercourse. Much has to do with the person’s immune system. Environmental pollutants and parasites can tax a person’s system and one can become more susceptible to infection while others, who do a good job of eliminating the environmental toxins from their bodies, and therefore have a healthy immune system may not get infected. This may be why some people believe that there is no such thing as HIV or AIDS.
My personal view is that the virus was released to the public by the powers that control this planet as a method of population control. Where it came from to begin with? Well, the scientific community says it came from Africa when a person received a bite from the Green Monkey. I’m not so sure about that and it could easily have been a manufactured virus.
