We need to go one further and separate religious reasoning from the political domain
Separating church and state is one thing, but we now need a societal disapproval of religious reasoning employed in the political environment. The sphere of politics should be based upon logic, science, statistics and progression. If we are going to develop as a society we need to decide what is good or bad for society based on logic and reason. Religion cheapens that debate and throws things off course, usually in favour or conservative traditional beliefs that may be out of date, wrong, or more likely, right, but not applicable in all circumstances.
