Ban religion from government, period. It cannot be discussed, cannot be used in laws, not one peep about it. People can believe whatever they want, but it CAN NOT exist in the halls of government buildings.
Public/elected officials don't get paid more than 30k a year. No bonuses and they get the same health coverage that everyone else in government does, and they pay for it themselves.
