Yet when you start trying to express what 'othering' might mean in plain English, you discover quickly that right away you lose the judgment that it is necessarily bad. In fact, even as a philosophical concept it isn't bad: it only became assumed to be bad when Critical Theory built out an argument that was adopted into theories of racism and colonialism. More basically, the idea of recognizing that some things aren't you is a necessary part of figuring out what is you, and thus what is yours. Recognizing that some things aren't yours is a necessary part of admitting to some limits on yourself: mind your own business means discerning what is, and is not, your business. Accepting limits on your own grasping will is an ethical value of the first rank.
To say that this is a process of discernment means also that it is a process of refinement. I am now figuring out what I like, and what I don't like. If we were talking not about racism but about, say, wine or fine coffee, we would in fact praise this sort of mindful experience, reflection, and then refinement of our tastes. Kant's Third Critique turns on how to do this well in what he thought was a universal and humane manner.
That doesn't mean that racism is good, of course. It just means that you now have to explain how this process of recognizing your own limits, of discerning and refining your tastes, can go wrong as well as go right. That's a much more interesting and useful discussion to have; and if you can have it in plain English, you can have it with a much wider audience.
