But the blog author seems to be an atheist or anarchist with this conclusion:
Ideology gives the evil-doer the steadfastness and certainty to keep going. Moral busybodies know no rest, for they cannot stop until the world matches their vision. Evil doers that find sanction in an ideology gain permission for their acts, a moral basis for evil deeds others might shun or condemn, and energy to keep going when a mere criminal might be sated with a dozen bodies.
Thus his ideology presumes to define what "evil" is, and in which contending for moral ideology is something that should be censored if contended for. His alternative is thus a ideology that has an animus to the promotion of moral ideology, which leads to anarchy and then dictatorship as an alternative to chaos.
But while the world abounds with examples of moral ideology being used for evil, as in Communism and Islam, this does not make moral ideology itself a problem any more than any education is itself. Instead it depends what is taught and how it was used.
The founders of the USA did not presume moral ideology was evil, but instead they depended upon a certain basic one. Under which souls were ruled from within so that smaller government, for basic functions, was enabled.
Washington's Farewell Address, 1797 — Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports. . . . And let us with caution indulge the supposition that morality can be maintained without religion. Whatever may be conceded to the influence of refined education on minds of peculiar structure, reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principle.

John Adams (1735—July 4, 1826. Second President and one of the Founding Fathers. Assisted Thomas Jefferson in drafting the Declaration of Independence) — "No simply form of government can possible secure men against the violence of power...Democracy will soon degenerate into an anarchy, such an anarchy that every man will do what is right in his own eyes and no man's life or property or reputation or liberty will be secure, and every one of these will soon mould itself into a system of subordination of all the moral virtues and intellectual abilities, all the powers of wealth, beauty, wit and science, to the wanton pleasures, the capricious will, and the execrable cruelty of one or a very few." (An Essay on Man's Lust for Power, August 29, 1763)
• ...we have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge, or gallantry, would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other. (From a letter Adams wrote on 11 October 1798 to the officers of the First Brigade, Third Division, of the Massachusetts Militia).ion of the Militia of Massachusetts,” October 11, 1798)
• Statesmen, my dear Sir, may plan and speculate for Liberty, but it is Religion and Morality alone, which can establish the Principles upon which Freedom can securely stand. The only foundation of a free Constitution is pure Virtue, and if this cannot be inspired into our People in a greater Measure, than they have it now, they may change their Rulers and the forms of Government, but they will not obtain a lasting liberty. They will only exchange Tyrants and Tyrannies." (Letter to Zabdiel Adams, June 21, 1776; http://memory.loc.gov/cgi-bin/query/r?ammem/hlaw:@field%28DOCID+@lit%28dg004210%29%29
Robert Winthrop (May 12, 1809 – November 16, 1894), and Speaker of the House from 1838 to 1840, and later president of the Massachusetts Bible Society, explained that, “Men, in a word, must necessarily be controlled, either by a power within them, or by a power without them; either by the Word of God, or by the strong arm of man; either by the Bible or the bayonet."
If we do NOT know what the evil is by now...
