@Khandro What beggars belief is your continuous carping, your continued defence of something that is petty and irrelevant - rather like the requirement to swear an oath to god, which the Scouts, rather sensibly, if a little late, are now minded to drop. Good for them! Shows that they at least are progressive, unlike yourself.
Gender. race and creed equality is not just a card you play in some game of oneupmanship except. it seems. in your mind - it's a fundamental lodestone of a decent, civilised society, and I am astonished that you would countenance a situation where those individual wishing to join the Scouting Association, but who do not believe in the monarchy might be excluded simply because they do not wish to lie and swear an oath they might not believe.
None of the fundamental values of scouting, or its principles, require allegiance to the monarchy. Being Trustworthy, self-confident and self controlled; having self-respect and respect for others (I would fail because what respect I have for you has vanished entirely); to work together and work toward a better society;caring for the natural world, respecting possessions and property - These are all values to be esteemed, and no one needs an oath of allegiance to the monarchy in order to activate such values.
None of those values require an oath to one particular god either, and the Scouts have recognised that, offering first a range of oaths depending on which particular god a prospective scout might follow- and now they are considering affirmation for atheists-those individuals who need no god to define their ethics or morals - an excellent and worthy change.
Given their earnest attempts to change and adapt to the cultural norms of a modern, liberal, secular democracy,it is a shame they do not go the extra mile and offer an alternative to pledging allegiance to the monarchy for those youths who consider the monarchy an irrelevance.
Like a lack of beliefs in any god, a lack of belief in a monarch does not make that person any less moral or ethical - but it does make them less prone to distort fact or lie in order to twist reality to better match their faith.
