Those who refuse to vote for a Government are rejecting aggression

It's not a very nice thing to do to force people to accept your offers, with the threat of violence. It's always best to allow people to refuse so that you can be sure you have not violated the rights of the other person in every transaction. If we are able to refuse then our rights have not been violated, by definition. We cannot complain if we can (are able to) safely refuse. An offer is not an offer if it not refusable, it is a command, which is not civilised.
