That was my impression also.
Granted I just skimmed the article (I usually just zip to the responses ... like now), but I thought he was just holding up educating barbarians as an analogy of how we need to educate people who don't know any better. Western society keeps denying the concept of sin, and media keeps projecting the idea that homosexuality is 'normal', and that it should be celebrated. This is teaching the people to become barbarians. No longer governed by God's laws, nor in reverent fear of His Name and presence.
I.e., society has become the person described in Psalm 14:1 'The fool has said in their heart that there is no God'...
I.e., we are brainwashed in the public schools and by the media to become fools and barbarians.
