How come Obama is so supportive of Muslims yet he is not equally supportive of Christians?

Religion should have no place in politics. I could care less about national prayer days for either religion. I don't care if Obama is Christian or Muslim, but the "right" keep putting out lies and will stop at nothing in attempts to slander the POTUS and to try to make the weak fearful of him because of his name and color. The GOP is really scary right now, and the teabaggers must be stopped before any of them end up in an actual place of power in the government. Come November, I sincerely hope that the fear tactics don't work.
