Convention, normalcy, and polite society are all very fine, yet civilization rests upon certain demands.
You are not far off, I do not criticize your intent, merely that as a denier of the “exogenous”, I wonder if you will be so hardline with your own when their treachery or corruption is made bare.
If you will say with me, “an incorruptible righteous rule of law” will save us, we are bondsman(and women) to a common critical cause.
“Them, they, and those other” however are not the threat to our lawfully protected free world. Integrity, and principle, and a continuity of “devotion” (human sacrifice) pays for civilization or it doesn’t.
Civilization will always have its rabble and unrest. Mitigating savage powers with a “civilizing accord” is the whole foundation of any.
