The eternal law of God is the sole standard and rule of human liberty, not only in each individual man, but also in the community and civil society which men constitute when united. Therefore, the true liberty of human society does not consist in every man doing what he pleases, for this would simply end in turmoil and confusion, and bring on the overthrow of the State; but rather in this, that through the injunctions of the civil law all may more easily conform to the prescriptions of the eternal law....Note how he slaps the Libertarians and Progressives who wish to live unbound: "...for this would end in turmoil and bring on the overthrow of the State...."
Yes. The Left-Libertines and -Progressives have been more aggressive and more violent--and they have actually tried to overthrow the President and earlier, Walker, in Wisconsin.
You can argue whether the turmoil will precede or follow the Left's moves. But 'civility' is no longer a requirement in response to Leftist moves.
(And by the way: a large number of Bishops and priests are attempting to overthrow the Church. One hopes that they are prepared for the turmoil which WILL follow.)
