Early Man - Girly Man

Ironcross at the Brutality of reason has a great theory about the development of early society and evolution of it's liberal elements. I laughed my ass off. Here's a bit:
"Division of the human family into two distinct groups began some 12,000 years ago..." "Some men spent their days tracking and killing animals to BBQ at night while they were drinking beer. This was the beginning of what became known as the "Conservative Movement". Other men, who were weaker and less skilled at hunting, learned to live off the conservatives by showing up for the nightly BBQ's and doing the sewing, fetching and hair dressing. This was the beginning of the "Liberal Movement"."
