True, gay people can enter into heterosexual marriages. As for the subsidy, I doubt that will change unless the affected group decides it has become too onerous and starts putting pressure on their representatives to remove it. Which means that more people getting married could shed more light on how unfair the system is for single people. It shouldn't have to be this way but unfortunately that seems to be how it goes.
