Enjoyed reading your  Mike, and glad that you shared your epiphany moment when you remembered Reinhold Niebuhr's insightful prayer about serenity. Is it a coincidence (or as Christians would say a Godincidence) that another pastor, Martin Niemoller, penned an equally striking statement that alerts us to the dangers of remaining silent.

"First they came for the communists
And I didn't speak up because I wasn't  communist.
Then they came for the Jews and I didn't speak up because I wasn't Jewish
 They came for the trade unionists and I didn't speak up because I wasn't  trade unionist.
 they came for the Catholics and I didn't speak up because I was a Protestant
Then they came for me and there was no one left to speak up for me."

Would serve the ANC MP's well to read both Niebuhr and Niemoller's thoughts when in parliament.
