I want to expound a bit more on my answer now that I have additional time:
I, personally, don't have a problem with other people's religions and have friendships with people of various spiritual beliefs. I respect and understand everyone's need for fulfillment and answers wherever they may be found. I was raised in a Christian household, was sent to a Christian school, but never felt any sort of conviction in what I was taught. After I made the decision to cease attending church, my mother told me one night (in tears) that it broke her heart that (because I am agnostic) we would be separated for eternity. It was fairly traumatizing that my mother, even though she loves me unconditionally, thought that I would go to "hell" because I did not subscribe to Christianity.
I understand more my Christian friends who look at the general philosophy of the Bible as opposed to those who strictly adhere to the literal tenants. My friends who are Muslim never freely talk about their religion, probably a force of habit due to the stigmatized status of their religion in this country.
