Room full of geniuses

I'll ignore the silly and degrading statements that the spokesmodel for the conservative 'Young America Foundation' made about women at the ill-named Values Voters Summit and just focus on the dumb one:

Mattera evoked the battle of David against Goliath as a metaphor for conservative college students who are ‘persecuted’ by the big bad liberals who control academia.”...
“‘David has the righteous answer,’ Mattera said, ‘because he is taking pride in his Christian beliefs.’

David's in the Old Testament dumbass, say what you will about him, but he wasn't a Christian.
