Mollygo Perhaps a new thread, but one that would likely get deleted within three posts.
I say true, it's human nature, we are instinctively tribal and communal, so we seek out others who we can identify with and group together with as strength in numbers is a basic survival instinct. We can only do that by observing and making decisions about whether others are friend of foe - we judge them, and they judge us in the same way because they are also trying to identify a like minded group whose principles and values will reflect their own, they also want to have the protection of a group. 'Othering' is what we do as humans, we cannot avoid it, we can't completely transcend it, all we can do is own it, be aware of it and recognise when it does true harm. As in racism and other 'isms'. No one group is ever right, just sometimes less harmful.
