In that country? don't count on it. At least not for MANY years (and revolution would HAVE to be bloody, that's all they seem to understand over there)
I tell you, coming from a family that feels the same way as most of these iranians-in-charge do, it's not an easy battle... I think best for now would be to make it easier for gay iranians to leave - who knows, maybe they'd be ok allowing the non-existing gays to leave the country.. i mean they weren't there in the first place, right?
