I'm not sure, baubles. At the very least, they seem to see it as an acceptable label, even though I pointed out that having humanist values does not make me not an atheist!
But really, I think they're just desperately short of leaders. They'll have to adapt or the scouting movement will collapse in favour of less discriminatory groups such as the Baden-Powell Service Association. Scouts within the original Scout Association are speaking out more and more as well, via the organisation called Inclusive Scouting. There's even a badge. I've sewn one on my uniform. The discriminatory die-hards may object, but I'll cross that bridge when I come to it. The only reason for wearing the badge is so that people ask what it's for. It's a badge for awareness-raising.
