I doubt this, in Pic. above, will happen in the USA but maybe in Europe ?
I remember, well over 30 years in our Congo. a Bro. started wearing one, along with slightly long hair, he was just making a come-back after an absence from attending, and was about to give a Bible Reading on the TMS, some of the Elders thought that he should not be allowed to give his Reading, but the TMS Overseer reasoned with them and he was allowed to, and wore it for a number of years.
He was eventually D.F'd for a minor matter, and after he got re-instated I noticed he had removed it, for obvious reasons I guess, to speed things up. He had a "smart" (shortish) haircut too.
But now ? How long before some do ? and how could any Elder do anything about it ?
"You won't be considered for "privileges" will not carry any weight, and maybe it will be a way for Bros. to AVOID "privileges" in the future ,as wearing a beard no longer works !
