Very hard to shake out the hatred once you have been brought up with it. People are fed with hatred from their infancy, they breathe hatred every day, they dream of hearted every night. France and Germany did this for two generations and it brought WW1. Germany and Japan did it again in the 20s and 30s and it brought WW2. Hamas, Likoud, Hezbollah and Republicans are feeding the same hatred to their members.
