It is not my job to work out how the agencies target the demographic which contains 78% of new male HIV infections, but it will have to be done and soon.

As Joe mentioned further up the thread, there are means of compulsion which do not involve criminalisation
If the agencies are not prepared to bite the bullet the time has surely arrived for male homosexuals to regulate themselves.
The "opt out" scheme seems a good start, this means that male homosexuals will be routinely tested when presenting themselves for medical treatment unless they "opt out and refuse to be tested.
The agencies seem quite keen on this.
