If you seek core principals, look to the US Constitution. I suggest the 1st and 2nd Amendments in particular. See anything in there that looks a little violated by the current political class?
Indeed. My point here is just that those Amendments do not exist in a vacuum, but are an outgrowth of the principle that all men are endowed by their Creator with certain Rights.
And, yes, the political class has strayed far from those principles.
