I don't think most people who hate Obama hate him because he's black. I think most people who hate him do so because they think he's a condescending liberal.
If Obama were a conservative, those same people wouldn't hate him.
Conservative emotions are so simplistic
They just can't disagree with an opponents positions, they need to hate the person
It wasn't enough to paint Obama as an inexperienced liberal not ready to lead. They had to attack his place of birth, call him a Muslim, make it clear he is not like "you and me"
The same now applies to Hillary.
With conservatives it is not a battle of political values, it is presented as a battle of good vs evil
