I know this has been dished over before, but when I was doing some research I discovered a couple of interesting points.
As far as I can find, there is only ONE WT article that implies that JW men should not have beards. Here it is:
*** w75 8/15 pp. 500-501 par. 9 - Do Not Let Yourself Be Ensnared by Fads and Entertainment *** Extreme hair styles can easily lead one into a trap of the Devil also, and cause others to stumble. For example, a young man in the United States was making fine progress in his study of the Bible, and he was moved to share with an experienced Witness in preaching to others about the good things he was learning from the Bible. From early youth he had let his beard grow, and since some in the business community wore beards, he felt that his wearing one in preaching to others would be acceptable generally. But in speaking to a lady he was unable to do more than introduce himself, when she said:
“I’m sorry, young man, I do not want to become involved in student revolt.”
No amount of explanation after this sufficed to clear up the misimpression. After the conversation ended with the closing of the door, he asked the experienced Witness what had happened. He was invited to consider his appearance in relation to what he claimed to be, a servant of God. Not wanting to be responsible for even one person’s being stumbled so as to miss the way to everlasting life, this new Kingdom publisher shaved off his beard. Would you be willing to do the same or to make similar adjustments if your appearance gave the wrong impression in a certain community? - Emphasis added So, let me get this straight: it's all because some un-named lady sometime back in the '70s or sometime earlier from "a certain [un-named] community" in some undisclosed location somewhere in the United States had the opinion that any young man with a beard would try to persuade her "to become involved in student revolt" JWs all across the world can't have beards! Well that seems perfectly reasonable to me! I wonder whatever happened to that lady? Do you think she knew she was making Theocratic Doctrine? She must've been one of the anointed, a member of the "Faithful & Discreet Slave" class, no doubt!!! Hmmmm, ...
