I find most of this article extremely enlightening on the foundation of many problems with modern life. I also, however, have issues with your examples concerning government and other semantic stop signs. Liberal democracy is not necessarily a stop sign. It is easily countered by asking what that has to do with anything, as no current country in the world has a true democracy. They have republics due to the sheer size of countries rendering direct democracy pointless. Also, governments are reliant on the intelligence of their leaders and on those who chose policies and laws. Stopping at Liberal Democracy means that you fail to ask about the possibility that the leaders are misguided or just plain wrong. With the nature of politics, there will always be one current political representative that a voter dislikes. Finally, there is one spot where a stop sign must be placed, and this is on right and wrong. I cannot foresee anyway in which an argument can be advanced past the point where morality dictates one action as better than another. There are explanations, but essentially right and wrong cannot be questioned, otherwise humanity may end up in a world much less pleasant than the current one.
