Odd what's allowed in Parliaments and Congresses. On a trip to Bermuda (the late 70s)I was fortunate to meet Robert Lowe who was the Parlimentarion for the Bermuda Parliament. He also announced the Monarch if and when she (or he) ever visited the Parliament. Anyway, Bob (a lovely man with a wonderful voice)said members were diciplined for using "bad" language. However, he noted, that there were some terrible epithets used and justified by fact they appeared in the Bible and so were non-diciplinable. It reminds me of what I was told the first time I assayed "Dam!" : "You may use swear words and vulgatities when you have mastered the English language."
Well ...........still workin' on *that!
