How do you deal with interfaith issues?

Talk things out. Alot of people choose to sweep religion under the rug especially if it affects a relationship. I am guilty of that sometimes with my in laws. They don't know a lot about a certain faith and what they know they learn from the Internet or media which is not always accurate. Sometimes I avoid the topic altogether instead of explaining to them that religion, in general, is a good thing, and it is people and their egos who make things difficult and awkward. Trust me, talk things out. Have a frank discussion. It will make things easier.
