Why is libertarianism so infallible?

Libertarianism is the inclusion of every sapient being into the decision making process and all that logically follows from that. Utilitarianism is the objective of ensuring the most happiness for all sapient beings and all that logically follows from that. Sometimes they compliment each other, other times they contradict.

The problem is, retard, you claimed bush was socialist because he was statist you fucking moron.

I did see communists and socialists get grouped together. Than social democrats joined them. After that, retarded Americans grouped liberals with them too, and now the pathetically retarded declare everyone not libertarian "socialist", even george fucking bush, because clearly their brain doesn't have the capacity beyond simple bifurcated classification. What's even sadder is, that these retards cling on to their delusions no matter what is the truth. They should put this retard on a documentary, on how he manages to stop at red lights and maybe even graduate despite having such a pathetically tiny mind that works on the simplest Aristotelean logic chains.
