Step in the right direction? Not going to make the right friends with this statement, I bet, but here goes:
I believe this is as far as restrictions should be lifted when it concerns MSM.
Honestly, given the high risk of infection even at this point, a fairly stringent regulation is needed; 12 months gives the best bet that the person will know if they have been infected or not, while any (or at least much) under that is still in the vague area of incubation time for many people carrying the virus (while not knowing they are doing so).
Putting them in the same placing as most other high risk sexual groups [those having sex with prostitutes, with IV drug (ab)users, and those who have sex with MSM] seems a very good step toward both health and equality. They are allowed, under the stipulations, to give blood [which is sorely needed, if it is anything like the US with donation rates] but does not discriminate [the reason is sound and true].
