There are only a very few reasons not to like Obama.
1 You are a bad person and Obama’s goodness underlines that fact by comparison.
2 You are dumb as a rock.
3 Life for you is pure misery and the image of a man and his family joyously at peace with the world makes you furiously resentful of the happiness of others.
3 You are an out and out bigot.
Can’t think of anymore reason.
