There are major flaws in Libertarian philosophy.
They are not particularly patriotic.
They are also pretty much anti-military, except for a sort of Switzerland model. Which has worked out fairly nicely for Switzerland, but it would have been nice to have their help through a few world wars. Including this one.
It’s easy to be ‘defense only’ as long as a big boy like America is handling the situations with its wealth and its blood.
Then there are the social issues, which make the Democrats look rather prudish at times. At least Mr. Paul is pro-life, as he recognizes the unborn human being as human. So a Libertarian can be consistently pro-life, if he acknowledges the humanity of the unborn.
Paul says that, and then devotes his life to promoting a pro-abortion libertarian agenda, and a pro-abortion party.
The libertarian goal is an America where abortion is totally unrestrained or limited.
