I believe we each believe what gives us comfort and helps us with our time on Earth. We cannot know, other than in our Heart and Spirit, what is True. Some people's expression of their beliefs can be like a secular gang or group's; loud and strident, and even abusive to others. The expression of one's beliefs is more about one's personality I think, than the beliefs necessarily. It is unfortunate because the expression can be done so poorly as to make it difficult for would-be listeners to hear and consider the beliefs themselves.

I think tolerance is necessary in one in order to hear and gain a measure of understanding of other people not like ourselves and to assure others that they will be heard. I believe your "friends" intolerance of what you believe and expression of it is about them rather than their beliefs. Intolerance is a hard thing to stand in the face of and get around so one can better understand.
