I wrote to the WT HQ about wearing of beards, in about 1974, they sent a reply which was full of the usual crap about why I shouldn't , but said they could not make a Rule for the whole WW brotherhood, it depended upon the attitude to beards in the country in which you lived.
I promptly grew a big one, and wore it for well over a decade, all that while I was a M.S and giving P.T's, even in neighbouring Congregations.
I was eventually told I could not be used on a Circuit Assy if I had one, so as I wanted to have my say in the bit I was assigned, I shaved it off. A sis. came up to me afterwards and said "You certainly tell it like it is !" , so I suppose it was worth it.
An Elder later said to me: " I hate what they made you do ". A few years later they used a bro with a beard at our circuit assembly in a similar item to mine. ???
But after that they still told guys with a beard, though an Elder, they could not be a head of a department at Conventions. They are seriously messed up.
