Voting is agression!
That's like saying guns are aggression.
A system based upon the tyranny of the majority (democracy) is an aggressive system.
A system based upon the tyranny of the most heavily armed (thuggery by force of arms) is an aggressive system.
Nonetheless we have the right to defend ourselves, even if we have to confiscate an aggressor's own gun for our defense against him or even if we have to use an aggressor's voting system to defend ourselves against statist voters.
Tools do not commit aggression, people do.
Since voting is an act, then it
can be considered an aggressive act, can it not?
The gun analogy doesn't really work, since it's an object. You'd have to compare voting to the act of firing the gun. Both are neutral actions, until you consider the intent....
.... which leads us to thought crimes.
