Yes libertarians are lefties who like conservative economics.
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.
Libertarians are for private control, not government control. Government is for doing those things we cannnot do for ourselves and for guarding our rights. Republicans and Democrats are all for strict government controls. As far as personal standards, that is for We the People, individually, to assert, not for the government to dictate based on what party in in control.
