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.

As you see, the retarded libertarian still claims that socialism is statism even though gallons of information disproving his retarded notion was given. Clearly, these retards don't have the intelligence to formulate any proper thinking, and they cling to their disproven delusions as INFALLIBLE TRUTH HURRR DURRR, which is expected from masses of uneducated morons.
