The MLA style manual (9th ed.) provides guidance for reducing bias language in writing.
Call people what they want to be called. Appropriate terminology changes over time, and not everyone within a certain group will agree with a label. Be sure to be sensitive to what you are calling people. (from MLA 9th edition manual).
The MLA style manual provides more guidance for reducing bias language in the areas of age, disability, gender, racial & ethnic identity, sexual orientation, socioeconomic states, and intersectionality.
