Sure there are, they just aren’t a majority. And as I said, their position is more consistent with libertarian principle than what’s in the platform.
The open borders position is coherent as long as it’s accompanied by a complete dismantling of the welfare state. This dismantling of the welfare state is in their platform, btw, and shows pretty clearly that libertarians are worlds apart from liberals. Or are we just supposed to ignore this little detail?
There it is, that is what makes the libertarians the commandos of the left.
Open the borders today, legalize all drugs and the homosexual agenda and all social liberalism today, and we will gladly pay you Tuesday.
Over the last 60 years the left and libertarians have made extraordinary breakthroughs in destroying the social conservative fabric of America, and they only create more liberal voters, it imports new liberals by the tens of millions, conservatism doesn't advance from that, it loses and is close to disappearing entirely.
