The ability to experience fear, worry and anxiety is a vital survival trait. Worry alerts us to potential problems; anxiety is a message from our subconscious that the problem is almost certainly real; fear is confirmation and the preparation of the body to deal with the problem, by fight or flight.
Alcohol allows a temporary change of perspective on reality, in the same way a ten mile run, a walk through the Louvre, or the contemplation of mitochondrial biochemistry does. Temproary changes of perspective enhance, rather than cloud reality.
Faith, in contrast, is the ultimate means of hiding from reality. Faith is the most effective way of rejecting evidence. Faith allows one, like Carrol's queen, to " believe as many as six impossible things before breakfast" yet to do so without his charm.
Faith allows one walk off a cliff, confident one will be unharmed. Faith allows one to immolate oneself and forty innocent fellow humans, confident one will awake in Paradise with a harem of virgins.
