Yes, Libertarianism is an essentially right wing ideology. There is no place for any types of Leftist thought in Libertarianism.

Libertarians and Left wingers get along because they have the following things in common:

1. anti-war
2. pro-drugs
3. pro-faggots
4. pro-abortion

However, anti war and pro drugs are not inherently Left wing concepts. As for faggots and abortion, those are admittedly Left wing ideas, but that doesn't mean Liberals can bring the rest of their bullshit along and call it Libertarianism.
