Hey, it's his book. There's nothing wrong with defacing or burning your own personal copy of a book. Historically, book burning has consisted of authorities rounding up as many copies of a book as they can in an attempt to control distribution of ideas. That's the sin.
Someone mentioned cherry-picking. The greatest example of that is the religious right's obsession with abortion, which is never mentioned in the Bible. But somehow they know God hates it. The Bible does condemn homosexuality, though Jesus says nothing about it. As for food, when the Pharisees criticize Jesus for not washing his hands before eating, he calls them hypocrites because washing one's hands is a tradition of the Elders, not a law from God. He then states that what goes into a man does not defile, but what comes out. The narrator interprets this as "Thus, he made all foods clean." This event takes place just a few verses after Jesus has said that the law will not change until heaven and earth have passed away. I have heard Christian leaders say that the law of the Old Testament applies except the parts that Jesus overrules. Funny that they still support the death penalty. In Matthew 5:37, Jesus says "You have been told an eye for an eye and a tooth for a tooth," but in the next verse he says "But I say unto you that if a man strike you on one cheek, turn to him the other." Weird.
