Thanks for posting that quote, anglise.
So if we take a look at the time that article was printed, what time era are we talking about?
Wasn't the hippy movement in vogue in the years preceeding it? Youth rebellion was a sign of the times, and a male growing his hear long was a sign of rebellion against authority. Compared to the conservative 50s and 60s, the hippy movement was the ultimate sign of rebellion.
Fast forward now to today.... the hippy movement is not what it used to be. Beards are now accepted in general business practice, just as women wearing dress slacks is acceptable. Beards DO NOT have the social stigma they once had.
So for elders, COs and the "powers that be" to rely on info from 25 years ago to say what is socially acceptable is a sad indication of what time frame their minds are living in.
