I would like to point out that one of the important reasons South African didn't descend into a race war at the end of the apartheid was the formation of the Truth & Reconciliation Committee for precisely this reason: to forgive and reconcile.
> South Africa’s ruling party on Tuesday defended the singing of an apartheid-era song with the words “Kill the Boer” in a row that has raised fears of increasing racial polarisation.
> The African National Congress dismissed a ruling by a regional high court last week that uttering or publishing the words would amount to hate speech and violate the constitution put in place after the end of white minority rule.
> “These songs cannot be regarded as hate speech or unconstitutional,” ANC Secretary General Gwede Mantashe told a news conference. “Any judgment that describes them as such is impractical and unimplementable.”
