As the kind Rabbi Kirshner once said (and I paraphrase)...

Any one who believes in a particular religion assumes it to be more "right" than other religions. That need not imply anything about our ability to both get along and explore our differences.

Seems to me that it is only the weak of faith (yes, even their faith in nothing) who get squeemish at the discussion of religion.
