This article says a group of atheists gathered to 'un-bless' a portion of highway with 'un-holy water.'
If they were really atheists they wouldn't believe any of that stuff, so why would it matter if the road were blessed or not? The fact that they take the trouble to conduct some sort of ceremony or ritual to 'un-bless' the road seems laughable, but is, in fact sinister.
If they really wanted to counter a Christian blessing they should have got some shaman or witch in to curse the place, and it is only a matter of time before they do so.
What the atheists don't understand, of course, is that atheism will eventually lead to the demonic. Nobody can believe in nothing for long. The atheists are not content to live as true atheists--minding their own business, imagining that they can live in a spiritual vacuum, and allowing those "religious kooks" to do their own thing.
No. They're not content to let religious people do what they want. Beneath their louche tolerance, shallow sophistication and affected nonchalance, their atheism is driven by rage so they have to try to close religion down, and when their meager efforts fail they will become increasingly violent and hateful.
They will then drift into new ways to curse God and destroy religion, and many of them will (either explicitly or implicitly) summon up and yield their souls to the powers of darkness. This is because it is impossible for a human being, who has an immortal soul, to exist in a state of non-alliance. You must serve either God or the Devil.
Already locked in a vile hatred of religion, they will find it all too easy to ally themselves to even greater powers of hatred and violence. Their God-empty souls will be vulnerable to every spiritual entity out there in the great chaos and taken over by evil, they will initiate a demonic reign of terror. More terrifying still is that they will do the most vile things and praise themselves for being 'free' or 'bringing about a new society.'
Do not imagine for a moment that atheism is ever benign. The atheists have always been out to destroy the church, and they will fight the faith with the tenacity and terror of the pit.
