Ignorance IS a major problem, but education will not overcome it easily. There are very well-educated folks who use supposed 'research' to support racist theories....and we have examples everyday of people just ignoring what they are taught & told in order to cling to some prejudice, superstition or cultural habit.

If education really solved things easily, we would not have astrology, palmistry, phrenology, Tarot, etc... (yes...and religion) coloring all aspects of life.
