Fuck off with that. Just because I haven't studied politics doesn't mean that I find liberalism and radical libertarians to be wrong. If I were to put myself under a school of thought when it comes to politics I'd rather associate myself with neorealism.
I bloody hate that argument "oh look at me, I've studied politics for 6/7 years therefore whatever you have to say is irrelevant". The most effective way of providing for the world? It's theory, your utopic state hasn't ever existed, therefore you don't know if it does in fact provide for the world in the most effective of ways. If theories worked out in reality as they do on paper we should all be living in Marxist states.
