I agree with you on the fact that non-voting is a powerful protest against the political system. But I believe that it's not the protest that will save us from the political system in which we find ourselves.
As Terence McKenna said:

The idea is not to confront bad ideas but to come up with good ones. Otherwise, your enemies define the game and you are the loyal opposition.

So instead of confronting this bad system in place, we must come up with another system that is better suited to fulfill the needs of the people. Or so I believe.

Thanks for the high quality post. Upvoted and Followed :)
