You tell me, Bob. Which of these are the real libertarians?
Or are none of them real?
Obviously the cartoons you posted are not of real people and the artist didn't bother to give any evidence that the views expressed were the actual views of any Libertarian.
In the photo you posted, the creator of that poster claims to be a Libertarian but doesn't give his name. For all we know, that author could have any beliefs at all and their poster could have been put up to sow confusion.
Are these posters advocating real libertarian talking points?
You're changing the subject.
The cartoons you posted started with a character saying that they were a Libertarian. Then all of the other cartoons had this stick character ask for government intervention. That's not Libertarian at all.
Since you have changed the subject, I assume that you are not disputing this.
Now as for your new question, here is the policy of the Libertarian Party's stated view:
Libertarians believe that people should be able to travel freely as long as they are peaceful. We welcome immigrants who come seeking a better life. The vast majority of immigrants are very peaceful and highly productive.
Indeed, the United States is a country of immigrants, of all backgrounds and walks of life…some families have just been here for more generations than others. Newcomers bring great vitality to our society.
A truly free market requires the free movement of people, not just products and ideas.
Whether they are from India or Mexico, whether they have advanced degrees or very little education, immigrants have one great thing in common: they bravely left their familiar surroundings in search of a better life. Many are fleeing extreme poverty and violence and are searching for a free and safe place to try to build their lives. We respect and admire their courage and are proud that they see the United States as a place of freedom, stability, and prosperity.
Of course, if someone has a record of violence, credible plans for violence, or acts violently, then Libertarians support blocking their entry, deporting, and/or prosecuting and imprisoning them, depending on the offense.
