Syphilis was the AIDS of its day.
Then penicillin came along, and people could sleep around without acquiring a fatal disease.
Naturally, AIDS came along and ended the period of being able to safely be promiscuous.
If we develop a cure for AIDS, something new will come along.
I wonder how many young non-maskers are spreading Covid the fun way? Also has Covid been found in semen or vaginal fluid?
Even without a cure, there’s drugs now that suppress HIV to the point that it’s hard to detect if someone has it, not to mention suppression of the disease progression. So we already have a license to be promiscuous even without totally curing HIV. As for syphilis, we have versions of syphilis that are resistant to antibiotics, brought on by promiscuous people getting infected multiple times by syphilis.
