@tepidpoultry, in the case of beards I haven't seen a male with a beard in the carts yet but I've seen brothers doing the microphones wearing beards or having parts in the meetings.
But, in the same kingdom hall there is one congregation allowing it, the other being completely intolerant.
In the my case, serving in a foreign-language congregation, aa there are congregations in other parts of my country where there are a lot of brothers from Central Europe, you can easily see brothers with beards giving talks at assemblies.
It's a recent trend here, I guess having a PM with a beard, a King that sometimes appear with a beard and many respected personalities with it in the last years plus the influence of neighbour European countries where it's a common thing have influenced elders in some congos.
But some years ago, the American rule of no beards allowed was the norm in all congos.
