Probably the biggest mental issue is the issue of black and white thinking. If you're not one then you MUST be the other. This attitude is ingrained in our society at all levels and it has never been true, but it does make thinking about things less of a puzzle, eases our road in life to make things simpler.
Everyone here should already be into the spectrum of behaviors rather than this simplistic black and white form of thinking, but to overcome this societal issue will take time. Little additional effort since life itself is complex and history is full of mature societies living in a more complex world than they used to live.
Show them a move called "Pleasantville" if they ever have a chance to overcome this handicap watching this movie will open their eyes. This is a great movie and it will bring out the emotions but it will blatantly expose the black and white thinking for what it is because of the purposeful use of Black and White images compared with colored images.
