That's a self-disproving statement. If it's true then it's false, which means it's true.... which demonstrates the existence of objective truth and therefore objective "right".
In response to Idaho, I would argue that doing what is "right" over being democratic, or more generally subverting the Constitution of the State is more something which is historically associated with the Left than Right, most of the overthrows of legitimate government in the last hundred years were by the Left, and most of current Despots are left or Centre; with the exception of Putin who is a result of a previous Leftist revolution.
