It is a very valuable observation you have made that most people do not realize. Folks tend to self sort themselves into those media outlets that will reinforce what they already believe and ignore and anathematize those that undermine their beliefs. We, as Libertarians, Anarchists, Voluntarians, and such fellow travelers as we are, have, for the most part, graduated FROM either the Right or the Left and so are Immune to either call and thus need not fear exposure to their ideas as we have already left them behind. The struggle is not Left vs. Right, that meme is Distraction. The Struggle is Freedom vs. Slavery, Up vs. Down. The Left leads to Socialism/Communism and the Right leads to Corporatism/Fascism, all just different brands and flavors of Totalitarianism, thus keeping the slaves of the Left vs. Right dichotomy distracted from the True Struggle, Freedom vs. Slavery. Those of us who do facebook might consider pointing out the fallacy of the Left vs. Right meme in favor of the Freedom vs. Slavery meme. It just might make sense to a limited percentage of them and win them over.
The things that will destroy us are: politics without principle;
pleasure without conscience; wealth without work; knowledge without character; business without morality; science without humanity; and
worship without sacrifice: Mahatma Mohandas K. Gan
