Voting isn't a right. It never was. Voting is a state granted privilege. The state decide votes and who doesn't. Rights belong to everyone. Citizens in other countries are not permitted to vote in our elections. Yet, citizens in other countries have the right to live. Voting is a privilege. Living is a right.
The rights to life, liberty, property, self-defense, procreation, religion, etc. are not contingent upon the existence of state. Rights exist whether or not there's a state. One doesn't have to ask permission to exercise one's rights. If one has to ask permission then it isn't a right.
