>>101171743That's a given, since unprotected anal sex is the highest risk form of sex for HIV transmission.
At current rates, 1/6 gay and bisexual men will be diagnosed with HIV in their lifetime. That's what the graph means. It doesn't mean that currently 1/6 MSM have HIV, it means that if nothing is done that will be the current trend.
However, HIV/AIDS is an area of large medical research, as well as increasing public awareness. Just a few decades ago it's causes and treatments were completely unknown.
Trying to take this data and put it as a part of a larger social platform instead of its purpose as a health initiative is dishonest analysis.
