"Change the behaviours alone withoput paying attention to the feelings behind them and all you are doing is creating a powderkeg."

Correct. You do not create brotherhood by intimidating and threatening people. You do not create brotherhood by establishing a climate of fear and accusation. You create brotherhood by engendering mutual love and respect in people, and uniting them in common (and positive) purposes.

The theme of "race" is constantly being used nowadays to intimidate and divide people...to make some feel like martyrs or victims and to make others (who have often done nothing wrong themselves) feel unearned guilt on account of past history which they were not the perpetrators of.

That's inappropriate. There's only one race of homo sapiens. It's called the human race.
