jack, if the whole MSM demographic was affected by HIV, it would only account for 1 in 100 of the whole population.
Would that mean that no swift and serious action should be taken to stop the "epidemic" amongst MSM?

To suggest that is ridiculous. I said already that in percentage terms, HIV is almost exclusively a disease of male homosexuality, in the UK and US.
Although new infections are only slightly higher for MSM, in real numbers, the percentage rates are massively different....and the percentage rates are what matter to male homosexuals.

If infection rates continue to rise in the MSM demographic at present rates, some real action will become imperative.
This demographic cannot wait for "education education", they have been immersed in "education" for decades.
