I don't know that it's against shaving the dome so much as it's addressed at the beard--but I don't know if anyone other than monks and eastern mystics shaved their heads in the 19th century. But it's spot on if you favor beards--it is a waste of time to shave. I've seen a number of guys not only w/ goats and shaved domes, but even full, mountain man style beards and clean scalps. Lots of quotes on beards: Wikipedia has several, two good ones I liked are "There are two kinds of people in this world that go around beardless—boys and women—and I am neither one." -Greek saying "A woman with a beard looks like a man. A man without a beard looks like a woman." - Afghan Saying.
Thanks for posting this as I begin the journey to repair the damage I did to my goat.
