Racism and anti-Semitism are some of the contentious issues that despite campaigns and educational programmes are still entrenched in the mind of many. In many countries where Jews have left in masses and no longer exist there, anti-Semitism still exists. This is handed down from parents to children.

Being straight on controversial attitudes in public will result just in extreme reaction on all sides.
