Maybe this is petty, but for someone like Obama who tries to claim that he is culturally superior, he should learn a little etiquette. In a setting such as this - it is considered disrespectful to have the sole of your foot facing the person you are talking to. And This is what O is doing to McCain. I hope he doesn’t pull a photo op like this elsewhere.
Muslims are paranoid about touching the bottom of shoes. Remember the mobs hitting Saddam’s statue with their shoes? Ultimate insult. So, was Obama the muslim doing this so his muslim friends could see he’s insulting McCain?
