Should religious ideologies play a role in politics?

As long as they do not limit civil liberties of other people, they can play a role.

If their contribution to politics is positive, i don't think that it should be a problem.

If someone's actions are moral because of his religion, than in my opinion its not a problem.

In my opinion, no. Because all of us have different views on life and the way we live it. If the religion gets involved then it makes it a bigger issue and might cause fighting or war.
