No polity without comity, and no comity without commonality.
E pluribus unum is a noble goal. But a durable and vibrant One cannot be made out of just any Many. Not just any diversity is combinable into unity.
This is why the oft-repeated 'Diversity is our strength' is foolish verbiage that could be spouted only by a liberal-left shallow pate.
We blew it as a society and now we are in trouble and teetering on the brink of collapse. No polity without comity, and no comity without commonality. The commonality that insures social harmony requires the stoppage of illegal immigration and reasonable limits on legal immigration together with the demand that potential immigrants be assimilable and willing to assimilate. But we no longer have the will to make that demand. We don't even have the will to protect the borders.
But of course foolishness about immigration and its effects is only one part of the explanation of our decline and eventual dissolution.
Still, we fight on, but only part-time because, being conservatives, we understand that the political is but a limited sphere. So ride the bike, traipse the trails, make music, draw and design, contemplate the constellations, make love to the spouse.
Above all, lift up your eyes, if you can, to a Reality superior to this passing scene, superior to this vain world whose vanity will vanish along with it.
