And of course there was the great American Liberator and subsequent round about father of what would become the American Civil Rights movement... Abrahaaaaaaaaaam Lincoln!

Lincoln, actually was reluctant to play the slave freedom card until after the civil war concluded, but played the slavery card to gain more political support with Europe. Oh and what a kick a** beard!
Freud believed that every woman suffered from p***s envy... The beard had nothing to do with it...

As equally obsessed with his sexuality, John Lennon sported a beard after finding himself through Eastern Mysticism

Isn't that smexy!
And of course there is the musician that some deem god, Jerry Garcia

Garcia's band The Greatful Dead were instrumental *(no pun intended) in popularizing LSD.
And should you ever consume too much LSD, you might come too in the presence of this guy...

Jesus Christ, a historical and religious figure who is cited in ancient texts, and the cannon books of two of the three "world" religions. Even the savior of humankind sported a chin rug.
In conclusion, a man who cannot grow a beard, is obviously unfit to: think, hold political office, liberate slaves, be a chovanist, explore Eastern Mysticism, popularize hallucinagens, or save the human race through ultimate personal sacrifice! Thank you, and goodnight.
