George Friedman said this quote

Secularism drew a radical distinction between public and private life, in which religion, in any traditional sense, was relegated to the private sphere with no hold over public life. There are many charms in secularism, in particular the freedom to believe what you will in private. But secularism also poses a public problem. There are those whose beliefs are so different from others’ beliefs that finding common ground in the public space is impossible. And then there are those for whom the very distinction between private and public is either meaningless or unacceptable. The complex contrivances of secularism have their charm, but not everyone is charmed.
