I very much agree with this. And more, I think the same can apply internally: our sense of self is really affected by what we tell ourselves. Of course it's important to be honest in front of ourselves, but too much self-deprecation can be just as damaging as external stigmas, if not more. I think it's worth learning how to stop negative internal talk and I believe this is what some therapists are trying to promote when they discourage labeling people with stigmatizing terms.
