Some dig in because they tulery care and want to protect their children.Some dig in because they are on a mission from God (after all, they talk to Him nightly).Some dig in because they are Evangelicals.Some dig in because they are Roman Catholic (old style).Some dig in because they are racest.Some dig in for something to get excited about.Some dig in because they are afraid.Some dig in because they are exceptionally strong individualists.Some dig in because they want to go back to a time that they believe that America was perfect (to them, anyway).This goes on and on.Common thread amoung all, does seem to be a total lack of will to even consider compromise (at least amoung those that I have met).
