I think they've caught a lot of crap about their pharisaic rules -- "going beyond these necessary things". Beards is just one of the most prominent examples of such and the issues happens to be a BIG issue for so many people because it is sooo obviously BS. Especially when beards have been allowed in some areas of the world, but banned in others. Our kids when only teenagers witnessed this when meeting elders visiting from Australia who all had full beards even though they were one of the "deadly sins" if you wore them here.
Hypocrites were not admired by Jesus either.
