Btw this is also one of the topics that show how JW cult teachings work.
There is no JW literature that states that beards are no good, let alone explain why.
However, all pictures always place beards with Satans followers.
School book states something about the need that brothers with a moustache should keep it neat....but no word on beards.
So 'beards are bad' is only implied, never stated in writing as that is an untenable position. But still every dub understands and complies.
And this is how they work...imply something but do not explicitely state it. Then you are never wrong, can deny everything, place the blame on those who 'misunderstood', and you can't be sued. 1975 anyone?
