I used to have a beard while going to meeting and got pulled aside and talked to but let the beard stay.
Beards according to many brothers is a sign of rebellion and they are half right because it is a sign of rebellions against the WT's prohibition,, and it is definately the start of "independant thinking" that the WT hates so much.
I reall beleive that Rutherford is responsible for the JWs being beardless,,secretly I think Rutherford had a strong dislike for Russell and when he became the WT dictator he had brothers shave their beards, and called it creature worship(Russell worship) if someone had a beard the only one he couldn't get to shave his beard was Van Amberg because he had too much clout.
