"When the Libertarian platform is just fine with queer marriage, sex with children,abortion, legal drugs etc, just how exactly do you think they will team with conservatives and take over the world?"
They wouldn't take over the world. They'd only join up with conservatives not social conservatives. They wouldn't get more than 15-20% of the vote, but that 15-20% would come more out of the republicans than democrats. This is why the republicans need to take them seriously to avoid it.
