I do not think that people really hate Obama. They dislike his policies.
His policies are increasing the debt to the level of default.
The problem with the pastor's point of view is that he regards taxes as charity.
Charity is the the free giving from one person to another.
The problem is that churches have become lazy. They are called to bring their laity together and take care of the poor and down trodden.
Instead, they would rather give their responsibility to Caesar and become a supporter of Caesar for more taxes and more goodies and at the end of the day they can feel better about themselves without really doing the job that they were supposed to do
