Don’t ever take a fence down until you know why it was put up.
Gilbert K. Chesterton
A frequently stated difference between a progressive and a conservative is that if they see a fence without any apparent purpose, the progressive wants to take it down, while the conservative does not want to remove it until he knows why it was put up.
I wonder how accurate that saying is — and whether there are studies to support it. But, yeah, it looks accurate.
