I think you should be able to have your own beliefs and not be discriminated against by a religion you are not a part of, they can, Of course, discourage what they think is wrong, but they cannot tell a person that they are sick or a terrible person for not following the laws of a religion they are not part of, this can be applied the same way, a person cannot tell a person of religion what they can and cannot do.
For this reason, I do not believe that a policy influenced by religion has a place, unless it benefits the majority of people, and does not hurt others.
