They'll tell you that you can have your religion in private, and then they'll make sure you're never alone.
When the modern world says to us aloud, "You may be religious when you are alone," it adds under its breath, "and I will see to it that you never are alone." To make Christianity a private affair while banishing all privacy is to relegate it to the rainbow's end or the Greek calends. That is one of the enemy's stratagems.
