"Othering" isn't "creeping" in. It's the core of modern systems. The fanatical competition that is our way of life is what fed a population of 8 billion mostly useless (to their own future) mouths. The principle "othering" is anthropocentrism, started by theology and continued with humanism.
The basis of most people's economic lifestyle is constructed in homes and schools teaching children that they must have an identity like an aristocrat, even if they nor the planet will ever afford it. Hating and exploiting other people is one of the ways to get there: especially if you master the 'art' of the Sale.
