To support a free country having borders is simply another way of saying: “A free country has a right and obligation to exclude from that country people who wish to undermine or eliminate that freedom.” Reasonable people can debate in what way to best achieve this goal, without sacrificing the freedom we hope to preserve. But how can you be against borders in principle? How can you be against any and all borders? How can anyone even slightly rational and decent be for “open borders,” which means: allowing anyone and everyone in, including known violent criminals; members of a violent cult with a track record of blowing up or beheading residents of the free country; and people who wish to spy on the free country’s government to hasten its obliteration?
If you’re against borders, you’re not only ignorant and foolish. I truly believe you’re evil. You know you’re making freedom impossible, and you don’t care.
