It is ironic that so-called free-thinkers avail themselves of this bunk.
The concept of an 'alternative' to scientific enquiry has a long history, rooted in the 1000+ year reign of the church.
It is the ever-shrinking world of the religious that attacks scientific prinicples, theories and discoveries and yearns for a smaller, darker world in which it's arbitrary and baseless superstitions could flourish, and with which it could exert its control over the hearts and minds of the people.
And so now, this anti-scientific tradition seeks the corners of our current understanding, the edges of the known world, to lie in wait - to masquerade its dying, final entrapments as post-modern; as liberal free-thinking into the 'real' nature of the universe.
The dark ages never went away, they just became 'new'.
