The military changed things for me. I have talked to a lot of ex-military people that say the same thing. If America is a melting pot, being in the military is a melting pot on steroids. For one, we were all on the same team, regardless of our leanings. We all took the same oaath the the former President, and every vet I talked to takes that oath very seriously, particulary the part that says "do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same"
I, _____, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God. (Title 10, US Code; Act of 5 May 1960 replacing the wording first adopted in 1789, with amendment effective 5 October 1962).
