Do it beardy! It's a conscience matter!
Just ask them to show you scripturally why you shouldn't have a beard. They won't be able to, yet you'll be able to show them how Yahweh feels about facial hair in the law code, he told them not to shave the extremities of the beard.. If they say 'we're not under that law now' then I think it's the same chapter that says he doesn't like tattoos, so you could say 'well, if we're not under that law anymore, I'm getting ink bro!'
Good luck!
