He was talking about your critique on Island's political system, obviously. As for defending the righteousness of the voting system, I'd just say that back then (when the democracy were employed) the people empowered to vote were only the citizens. In those times it made sense to consider citizens those whom the society could count on to defend its existence. Those would be, objectively speaking, the individuals invested enough to stay and defend the city/country with their own life if necessary, otherwise there wouldn't any assurance that the civic-responsible (and interested) voter wouldn't make himself scarce at first sign of trouble. So no, not everyone deserved to vote (back then). Let's talk about women's condition - could women have any influence in politics? Perhaps! But when the time did come, women were powerless in regard to enforcing decisions and more - like it can be deduced from the reference that user ableal provided¹, the women were spared and treated like objects rather than subjects of decisions' consequences. Nowadays (almost) everyone has a right to vote because everyone who votes has more or less the same footing (men and women alike). Now the system is supported (on the individual level) through financial contribution, and everyone supporting (i.e. empowering) the system should have at least some power, expressed through vote. So yes, everyone deserves to vote (now).
