I oppose most restrictions on travel between countries. Putting up walls to keep people out also keeps us in. The right to travel is a natural human right, like the other rights, i.e. freedom of religion, freedom of speech, the right to life, liberty and the pursuit of happiness, etc.
The death penalty is way wrong. So many people are wrongly convicted, at least 10%. Only God knows who deserves to die. Murderers can repent and be good Christians like anyone else can. The prison system is a for-profit institution based on greed, like much of the corruption in our society. We have way too many imprisoned for trivial offenses as well as wrongful conviction by corrupt officials.
Do we hear from the Free State Project around here? That's a libertarian effort, you know. I write a lot on their forum at
