These are what the mysticism the Einstein Dingleberries hypnotized
themselves in **believing in**. <shrug>
When given the truth, the Einstein Dingleberries still whining about
their mysticisms fed to them daily. Oh, well. Mysticism is only a
small part to the BS diet fed to Einstein Dingleberries where:
** FAITH IS THEORY
** MYSTICISM IS WISDOM
** IGNORANCE IS KNOWLEDGE
** PLAGIARISM IS CREATIVITY
** CONJECTURE IS REALITY
** BELIEVING IS LEARNING
** LYING IS TEACHING
