Ian old pal, I have been quoting HPA figures for years, get up to speed mate :0)
For all your twisting on the hook, the telling statistics are.

2/3% of the population(MSM), account for 60% of all new cases of HIV and 70% of all new cases of Syphilis. Other STDs have slightly lower rates, but still many times higher that heterosexuals.

It is impossible to distort these figures, they are set down in the HPA and CDC websites, there is no way to make them look better or worse than they are.

Both the HIV and Syphilis figures indicate epidemic rates amongst MSM, this is why I favour compulsory testing and contact tracing.
If these rates of infection were duplicated in hetero men or even IDU's I would favour compulsory testing and contact tracing for them also, but to test the whole population of the UK or the US just to validate a politically correct agenda, would be crass foolishness.
