D-Rob also doesn't go around saying people he doesn't like are the antichrist.
He's what Christians and role models should aspire to be - smart, successful, upstanding citizen, and serves the community. He does talk about God a ton but from what I've seen its only during occasions where he's talking about himself. He doesn't go around quoting the Bible to fulfill a hater's agenda and how guys like Obama are the anti-christ.
He uses his religion to motivate himself and not to on science (being a math major in the Naval Academy helps too) nor does the Admiral use it as a tool for hate unlike the dumbass mobs that use it to persecute and on others.
