The core component of politics is: Forcing people to contribute. Without the force there is no politics.
From North Korean despotism to Swiss (or Californian) direct democracy this core remains. Although they are very different systems the central injustice stays intact: Some people are forced to contribute against their will.
This injustice does not suddenly go away when 50%+1 of the people agree on an action. In this case 50%-1 of the people are being force to contribute to something they don't agree with. That is a plain injustice. It doesn't even go away when 100%-1 agree on an action. Injustice against one person is still an injustice.
So, to all our friends on the left whose almost daily mantra is a railing against injustice? To be consistent you must also do what we on the right seek to do: Limit politics to the smallest sphere possible. Fight the Injustice!
