There are always points of interesection between people and groups. That does not mean they are in agreement, or that one embraces the other. The John Birch society is a very conservative (VERY) ogranization that is against almost any government, and so are libertarians.
However, the histrionics behind each are vastly different, as are their intended means and demigoging the way to lessen the government's role. Tarring Libertarians with the brush of The JOhn Birch Society, is sadly, what the democrat party has become. No longer able to debate ideas on their merit, they must now label anyone who does not agree with them, to be some type of hate monger (race, religion, color creed, etc.). When in fact, the only ones injecting hatred into the debate are the democrats themselves.
For a liberal to hate what Ron Paul stands for is a given. It is their antithesis. And sadly, I guess I expect them to then use their fiery rhetoric to try to paint him and all his compatriots as racist hate mongers. For it is now apparent that their only retort to an intelligent debate is to brand their oponents with the image they see in the mirror.
Sad and expected, but still not right.
