Everyone, in any society, no matter where or when they live(d), is exposed to, trained in, and affected by their culture, their 'group think', and the propaganda fed to them from the time they are born to the time they die. I recently realized again just how early this starts, and how much our minds really are manipulated in everything from very small thoughts to very large ideas when I had a short exposure to what is overall a very nice children's cartoon.
