It's all about the golden rule. Plus respect for one another, even if there are differing views.
I share things that I like. Who knows, you may like it too.
I do solemnly swear 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, "unless he is illegitimate", and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God.
