The reality is that libertarianism has an agenda, and that agenda has advanced incredibly over the last 50 years.
Libertarians are an incredibly dishonest bunch and will lie about most of what they stand for and fight for, and believe in, in an effort to always shape their cultish arguments for whichever audience they are speaking to.
Here is the leftists agenda hidden behind the Libertarian Party curtain.
Libertarian Party Platform:
Throw open the borders completely; only a rare individual (terrorist, disease carrier etc.) can be kept from freedom of movement through political boundaries.
Homosexuals; total freedom in the military, gay marriage, adoption, child custody and everything else.
Abortion; zero restrictions or impediments.
Pornography; no restraint, no restrictions.
Drugs; Meth, Heroin, Crack, and anything new that science can come up with, zero restrictions.
Advertising those drugs, prostitution, and pornography; zero restrictions.
Military Strength; minimal capabilities.
