It's very wrong that having HIV achieved de-facto civil rights status. A person has a contageous and fatal disease that has no cure and they have a right to go wherever they want. No one that they come in contact with has to know that they have HIV.
HIV is a nightmare disease. If you wanted to conjure up a science fiction space virus you would be hard pressed to imagine a worse disease. It's 100 percent fatal and it's incurable. It has a long latency period where a person might be a carrier but have no symptoms for as long as a decade.
But even an incurable disease can be controlled by contact tracing and isolation of infected individuals. The fact that this wasn't done is criminally negligent. The AIDS epidemic if one of the crown jewels of 20th century liberalism.
