Apparently in some congs in the UK there are a lot of Polish immigrant JWs and their JW culture doesn't permit the beard. They then force this on to their native brothers and sisters claiming to be offended if a Brit was allowed on a platform with a beard.
If I was still in the UK and that happened to me, I would direct them to the nearest airport and tell them they'd be best off in their own country instead of having the gall to force their culture on the locals.
The very fact that someone gets shocked by a beard and then has the audacity (not that great freeware music software) to claim to know your "weak spiritual attitude" and determine your right to be a good Christian based on having a beard is beyond me!
