Insisting members are no part of the world. Ridiculous, we have to live on this planet. Sure be an individual and join in whatever you like and don't necessarily be a sheeple but forbidding people from being a part of the culture they're growing up in is damaging to their mental health.
Children want to join in, to be accepted, to make friends, that's normal. Preventing them doing this, I believe, is actual cruelty.
