Dr. Mod proposes a new theory.
I am setting forth the theory that the true Liberal, might be a sub specie of pithycanthropus man, a specie thought to have died out millenia ago.
The behavior exhibited today closely mirrors the very first group behavior, such as huddling together and screeching since they had no formal language. The use of grunting was first thought to be credited to this diverse group and anthropologist believe that there very first coherent utterance was along the lines of" Bush's fault".
Sexual behavior was initiated by the female of this species, since the males were weak and easily led about.
The female of the species was characterized by extremely hairy faces and armpits {see sub-specie Frenches stinkus}.
The male of the species is known to be extremely weak minded and physically shortchanged in the penis.
How they have survived for so many years after thought to be extinct is causing considerable consternation among scientist worldwide.
