While our society is tolerant and welcoming of all religions, its foundations are not based on Buddhism or Islam or Animism, for that matter. Our society, our system of government, and frankly the things that make our nation great stem from its Judeao-Christian heritage. To the extent that we remain connected to that heritage, we will survive as a people. If we lapse into multiculturalistic relativism as you appear to suggest, we will decline and fail.
Any specific Christian denomination? And are Roman Catholics allowed in?
