Look, I feel sorry for people who are HIV+ due to one mistake, that they were duped by someone who knew they were HIV+ and infected them. One would think that these innocent HIV+ people would think that quarantining those who infected them in the first place is too gentle and wish that their killers would be shot.
People who are HIV+ and ACT RESPONSIBLY -- i.e. TELL their prospective partners before engaging in activities that may infect them and take serious precautions are OK in my book. But if most people acted that way, we wouldn't see the continuing spread we see.
But since clearly most of those who are infected are more interested in their own pleasure and don't care how many people they kill, to satisfy their urges are plain and simply killers and need to be removed from society, to keep them from murdering other people.
In highschools, since you asked, I believe in EDUCATION -- people who practice abstinence don't get STDs and they should understand that one mistake can literally doom them for life.
If these 4 guys, now knowing they have a strain for which there is no known treatment, go out and have unprotected sex and they pass along the virus to others who die as a result, who is "innocent" there?
