It is not a sign of weakness to protect our borders any way we see fit. It is a sign of strength. Having secure borders ensures our liberty, it does not take away from it because we can leave and come back anytime we want to, so where is the loss of liberty? This country has been very generous to immigrants and has taken them in more than any other country on this planet. But our generosity has been abused my millions and million of illegal aliens crossing our southern border. This is not the case with our northern border with Canada. We need to secure our southern border where most of the abuse is occuring and then see what needs to be done with our northern one, if anything. There has been known 135,000 OTM's that have snuck across our southern border from known terrorist countries in recent years. No one knows why they are here or where they are or what their intentions are. This is what is a real threat to our "liberty".
