Wrong. The left HATES this stuff. It destroys their abilty to cast Wsern Civilization as the "bad guy". Believe me, the folks trying to debunk the new research on pre-Columbian conditions in the Americas are universally leftist.
Huh? You think the propaganda that North America was thickly populated to the tune of 100,000,000 people, with a widespread, prosperous agriculture, 95% of which was wiped out in a holocaust of diseases brought by the white man, whose devastation returned most of the continent to wilderness is a conservative theory??? If so, Ward Churchill is a Republican.
