No. New HIV diagnoses in the US are 67% male-to-male sexual contact, 22% heterosexual contact, and 7% injection drug use. (BTW, I have no agenda here except accurate statistics.)

According to [0] in 2020, MSM accounted for 71% of new HIV diagnoses, while people who inject drugs (PWID) accounted for 7% of new HIV infections. AFAIK similar stats are also for western and central Europe. These are population-level stats, not relative risks, but If we disregard PWID and scale to population size, MSM are still one to two orders of magnitude more at risk than non-MSM, non-PWID population, so they are clearly disproportionately affected.

This is not true. In 2018 in the US, 66% of new HIV diagnoses were in the transmission category of male-to-male sexual contact:
