You need to be practical though. Trade is important. Tourists are important. I'd have no trouble going into a country to deliver iphones or take pictures of their historical sites if they said there was no way I could ever become a full citizen or have voting rights, but I wouldn't go if I had no rights and could be robbed or murdered at will. I suggest solving the woman problem by stating that the vote is one family, one vote. The male casts the vote, but he must be married and have at least one biological child.
