Here in Australia, it is frowned on for any appointed man.
I reckon it is just because it has "always been that way, hence it can't possible be acceptable to wear a beard!"
But what about the many appointed bros who have long sideburns, or moustaches?
Such inconsistent reasoning!
There is NO scriptural reason for not having a beard...(in fact there is scriptural reason TO have one!)
But, if a bro grows one...it will be slammed under the 'disrespectful brazen conduct rule'
