Ian says, that, "as more people come forward, HIV numbers go up."

That statement completely and deliberately misses the point.
The important factor is not numbers of infections, but new infection rates.
These new infection rates now stand at 65/70% for MSM and have risen at a consistent rate for the last decade.
The rates in all other demographics are falling, including the rates for IDUs

It is frightening that someone who claims to have held a responsible position in health care, either does not understand the data produced by reputable health agencies, or worse, deliberately misrepresents it to bolster his "equality" agenda.

Regarding "compulsion", if some start is made now, to make testing available for those who really need it......Clue here....the demographic which is massively more affected than all of the others put together, though constituting only a tiny fraction of the population!! the compulsion may be avoided.
However, if something radical is no put in place to halt the epidemic soon, "compulsion" will be inevitable.
