There is this strange belief that humor is exempt from consequences.

In the book “Jam” by “Yahtzee Croshaw” there is a post-apocalyptic sect formed by a group of people from an internet forum. They are not stupid of course; they form a sect ironically. Then they worship a rambling drunk old man called Bob ironically and have ironic sermons and ironically imprison nonbelievers at the ironic orders of the High Priest.

If you point out that this is stupid and evil, they will roll their eyes and go “Duh!”, then ironically execute you for heresy.
