I think we humans just have varying levels of need for the irrational, and it's best for everyone that the irrational be safely available - which includes a certain degree of social acceptability. "Acceptable crazy," as you say. Note the increase in Icelandic belief in elves as their society's attachment to Christianity wanes... My personal favorite flavor of irrationality: liberal Christianity - the Episcopal Church, to be precise. Just enough of the mysterious and traditional ritual, paired with acceptance of the reality we must share with everyone. We voted to offer same-sex marriages church-wide a few days after the US Supreme Court required it nationwide, and have long believed that science is best left to the scientists. But it's probably not enough irrationality to satisfy most people, as every time we shed a little of the irrational, we shed members.
