Well, according to the CDC:
Gay, bisexual, and other men who have sex with men account for 70% of new HIV infections in the United States.
New HIV infections among gay and bisexual men overall remained stable in recent years.
More than 600,000 gay and bisexual men are living with HIV in the United States.
I do believe Stevie Wonder could see what the root cause of HIV is...
Even more is the fact that that 70 percent comes from a small fraction of the overall population.
