Rightwing fruitcake fundie James Dobson is upset that Obama knows the Bible is a poor choice for a governing document.

In comments aired on his radio show Tuesday, Focus on the Family founder James Dobson criticized the presumptive Democratic presidential nominee for comments he made in a June 2006 speech to the liberal Christian group Call to Renewal.

In the speech, Obama suggested that it would be impractical to govern based solely on the word of the Bible, noting that some passages suggest slavery is permissible and eating shellfish is disgraceful.

“Which passages of scripture should guide our public policy?” Obama asked in the speech. “Should we go with Leviticus, which suggests slavery is OK and that eating shellfish is an abomination? Or we could go with Deuteronomy, which suggests stoning your child if he strays from the faith? Or should we just stick to the Sermon on the Mount?

“So before we get carried away, let’s read our Bible now,” Obama said, to cheers. “Folks haven’t been reading their Bible.”

Dobson also takes aim at Obama for suggesting in the speech that those motivated by religion should attempt to appeal to broader segments of the population by not just framing their arguments around religious precepts.

“Democracy demands that the religiously motivated translate their concerns into universal rather than religion-specific values,” Obama said. “It requires their proposals be subject to argument and amenable to reason.”

Keep digging, Jimmy. Keep digging.
