Religious liberty necessarily is conducive to suppression of religion in the public sphere. While it attempts to protect individual freedom from coercion it reduces all religions to the same level of irrelevance. From the ashes of a fallen Christendom, a pathetic carcass of secular morality rises up due to the absence of a vital Catholicism. When all that matters is not the truths of religion but the mere option to choose, it should cause no surprises that when the content of one of these systems demands a bit too much to be comfortable for the rest, it will be ruthlessly put down.
Instead of promoting the rights of God, we have falsely adopted the right of man to form his own understanding of reality, which is of no more validity than anyone else's.
