The real reason that public health authorities have promoted condom use (ever since C. Everett Koop did in the 1980s) is that if enough gay men use them, the rate of transmission of HIV might drop enough so that the AIDS epidemic would slowly burn out, or at least be contained. There is evidence that this strategy worked, at least for a time, as the 1980s generation of homosexual men did practice "safer" sex. (Now the younger generation of homosexual men are said to be less cautious, and HIV transmission rates are increasing again.)
The CDC does say, very plainly, in its guidelines for HIV prevention, that abstinence (or monogamy with an uninfected partner, i.e., marriage) is the only way to be completely sure you won't get HIV. Odd how the bottom line recommendations agree with what the Bible teaches.
"It has also been established that the AIDS virus is smaller than the pores of latex condoms. "
The HIV virus has never been isolated.
