No, there have always been people like yourself, filled with hate for those who seem different, because they are black, or ginger, or Irish, or Catholic, or Protestant, or Royalist, or Republican, or heretic, or deformed, or ill, or poor, or Palestinian, or foreign, or Muslim, or Jewish.
You like to vomit out your hatred and spread it around.
From time go time some of them get into a position where can can get enough influence or power to put their hatred into action. You like walls, and ghettoes, and expulsion, and separation, and camps, and disposal.
