Do people with different religious or philosophical beliefs have a good relationship?

What can agree upon, what differences will you need to accept, and what would be dealbreakers?

How can agreement on values overcome these differences?

Is the disagreement based on beliefs, the rituals, or the history that comes with that religion or philosophy?

How do you raise your children if there is a difference in beliefs?
