La Shawn Barber is talking about Liberal Theology and scripture.
One of the big problems I have with liberal theology is one of their first tenets is a rejection of the inerrancy or validity of scripture. This means that when they do seek to use scripture they almost inherently pervert it. Why? Because they never seem to fit things into a coherent scriptural ideology. The biblical use for scripture is as a ruler or standard. By rejecting this they try to impose their own ideas onto the word of God. Unfortunately once you start throwing the portions of the bible out that doesn't support your conclusions you can follow anything.
For instance Christ said "Blessed are the peacemakers" yet he himself made a whip and cast the moneychangers out of Gods temple. Liberals like to portray anger or hate as a negative emotion and inherently sinful. The problem is that we know from the Bible that God hates sin and becomes angry with disobedience.
