I take it that was a point of order. The test of a point of order is whether it is disruptive in the House. Although the member just raised the point of order, I did not take it as being a disruptive comment.
If I find otherwise I will come back to the House with respect to words that have been ruled to be unparliamentary. Having read Beauchesne several times, I am not sure that Mr. X is an unparliamentary word, but I will be happy to look at it and report back to the member.
