letting the whims and styles of society at large dictate what they do. Early 1900s it was common for distinguished men and world leaders to have beards. Then they went out of style. It may cycle back around, and then they'll change the policy I would expect. It's probably the oddest, most uncalled for aspect of the honor code. God put beards on men's faces after all, it's not something we just invented to be rebellious or some silliness. They can look good and lots of women prefer them too.
