According to Peter (alt.conspiracy, 10th December 2003) Freemasons are, in fact, aliens:
The Freemasons are an organization of extraterrestrialbeings, closely linked to Zionism, who cross-bred with earth humans long ago. Not all of them actuallyjoin the lodgenor make public their association with this organization. They are the descendants of thefallen angelsof Biblical lore who cross-bred with the daughters of men creatinggiants(seemingly human beings with advanced abilities compared to earth humans.)
We can apparently defend ourselves against them by smoking more dope.

You know, that description almost makes it sound worthwhile to join the Masons...
