You really are deceived. My youngest brother died of organ failure brought on by a suppressed immune system due to HIV, which he got from a partner who died due to HIV. He was 42.
Gay men have unique health problems associated with their "lifestyle" and to say otherwise is to deny medical truth.
As to all Christians being homophobic that is an outright lie. I know more Christians who do not have an irrational fear of gays than those that do.
If your partner was diagnosed HIV+ in 1990 how do you know he was positive in 1981?
No one dies of HIV infection. Pnuemocystis cariini pnuemonia was the cause of death in 60% of early AIDS patients, however the pathogen that causes PCP is in the lungs of all humans and it takes a suppressed immune system to allow the disease to become active. The same is true of most, if not all, of the opportunistic diseases that take the lives of AIDS patients.
If anyone is controlled by the devil it is those who lie about what God's perfect word has to say about same gender sexual relationships.
