"Borders" are a boundary violation. Supported by people who don't understand their boundaries and don't respect the boundaries of others.
This isn't to say that those who cross "borders" understand or respect boundaries any better. Many of them don't; trespassing on private property, littering, stealing, and otherwise archating. But how can boundary-violating hypocrites preach respect for boundaries at anyone else with any credibility?
They can't.
