One thing I noticed in particular as I looked at these movements (whether big or small) is that  the struggle between fear and courage is always at the forefront. As I made my way to present day, I reflected on how badly some people want a wall between the United States and Mexico. While I won’t pretend to know the first thing about border security, I do know that if we’re putting up walls, figuratively or for real, it’s because we’re afraid.
