This is not true concerning the content, but it is often true concerning the using. One can make oneself invisible by talking about the other one's strangeness. The heterogeneity within a group that is “othered”, is made invisible. Sometimes "self-ethnicising" is used by marginal groups to claim a position for self-articulation and empowerment. In this case, the heterogeneity of the group is also made invisible for strategic reasons. Gayatri Spivak, a post-colonial theorist, calls this “strategic essentialism”. It means to refer to an essentialist category (like “women”) for reasons of explaining a (political) position that is usually marginalised.
