I've seen a couple of these things now, mainly in South Africa, but I thought I'd enter this as a discussion/ opinion piece.
My intention is not from a racism angle. I'm wondering if a consistent group of similar individuals got together (from a realistic perspective) and started their own community/ town (taking themselves away from 'normal/ standard' society), is it something you would consider joining?
On the face of it, I don't know if I would class these actions as 'racist' if they're not doing harm to others with their views or actions (until that changes). I think it's a 'preference', but one that is all the more poorer from excluding other Humans from interaction. However... I think the participants, in this case, are intertwined with (knowingly or unknowingly) the indoctrination of a dark ideology.
