    Electrical theory is a branch of science, and by extension what we call science is a branch of understanding life. White goes with white. Black goes with black. Yellow goes with yellow. Brown goes with brown. Red goes with red.

    That which is natural ought to be preserved, not defiled or desecrated. Our civilization has been self-sabotaging it's own roots and foundations for too many decades ever since the "civil rights movement" which basically was the prelude to our own self destruction and downfall as a civilized society. No, I'm not a baby-boomer. Good luck to all my fellow millennials trying to succeed in the trades. May the good lord shine upon all who try to walk in the light of naturalism and due reverence toward our founding fathers and mothers who made Western Civilization's prosperity possible in the first place. Our hands. Our minds. Our cultures. Our government infrastructure(s). Made for us, by us. Yet of course, we're not allowed to say it. Truth will not be televised.
