2. "Moronic sheep" is a poetic way to describe people who tend to trust lies they've been force-fed, without questioning. I blame the lack of critical thinking, groupthink, and deep internalized 'herd following' attitude nurtured from schools to colleges.

I guess anti-individualism is the best way to call it. I always refer to excellent "Excellent Sheep" book by William Deresiewicz who succinctly described just what I experienced first hand during years of Ivy League un-education.
