@Pseudonymous. I don't find your use of the sociological term 'other' outside an academic context helpful. Your brief explanation doesn't make sense to me - for elderly people are regarded intrinsically different from, presumably, non-elderly people then 'intrinsic' must have a meaning diferent from the one in the dictionary. See a longer discussion of usage https://www.merriam-webster.com/words-at-play/other-as-a-verb

In non-specialist usage you get daft things like people resenting being 'othered' and then forming campaign groups for their particular concerns.
