I would not have thought the remarks were that controversial. I expressed similar views in this blog on 28th November, and I was not alone.
"You are old, father Gordon," the young man said,
"And your hair has become very grey;
And yet you incessantly stand on your head
Do you think, at your age, it's the way?
"In my youth," father Gordon replied to his son,
"I feared it might injure the brain;
But, now that I'm perfectly sure I have none,
Why, I do it again and again."
Thanks and apologies to Lewis Carroll.
