If walls are so immoral, as a certain political party suggests,

North Cape May - If walls are so immoral, as a certain political party suggests, then why are they around every prison, military installation, and even countries such as the Great Wall of China? It is meant to keep people out or in. I dare you to go to a nuclear sub base and tell them walls are immoral. Just try to climb over our own U.S. Coast Guard base and see what happens.
