For context, here's an excerpt from the more recent WT article: Does Your Style of Dress Glorify God? (The Watchtower, September 2016, Study edition, pages 17 - 21, paragraph 17):
What are some factors that may affect whether a brother wears a beard?
17 What about the propriety of brothers wearing a beard? The Mosaic Law required men to wear a beard. However, Christians are not under the Mosaic Law, nor are they obliged to observe it. (Lev. 19:27; 21:5; Gal. 3:24, 25) In some cultures, a neatly trimmed beard
may be acceptable and respectable, and it may not detract at all from
the Kingdom message. In fact, some appointed brothers have beards. Even
so, some brothers might decide not to wear a beard. (1 Cor. 8:9, 13; 10:32)
In other cultures or localities, beards are not the custom and are not
considered acceptable for Christian ministers. In fact, having one may
hinder a brother from bringing glory to God by his dress and grooming
and his being irreprehensible.—Rom. 15:1-3; 1 Tim. 3:2, 7.
A careful reading of this paragraph reveals that it doesn't really say anything definitive one way or another. It is notable for being abstruse, that is: difficult to understand for its lack of clarity on an issue about which many people would like just that--clarity and a definite stand.
I could easily argue any position--beard or no beard--from this wishy-washy, obfuscating drivel. So again, it just comes down to whatever the local elders are going to allow and/or prohibit. But they don't make rules. But they DO have the position of authority according to the religion's hierarchy and power structure. They have it and you don't.
Again, it's NOT about doctrine or "Bible principles" no matter how frequently they say so with all the appropriate hand-waving; it IS about one thing: CONTROL.
