Why are lefties attracted to New Age religions?

[yurbud]

While most religious people on the right tend to be fundamentalists or traditionalists of some stripe, more on the left seem to take an interest in New Age stuff.

This seems ironic since the left is usually more rigorous about requiring evidence before they believe things in other areas of life, and will rightly criticize the Catholic Church and Evangelicals for irrational beliefs, but then they turn off their BS detector as soon as someone mentions crystals,shamans, or reincarnation.

Any explanation?
