I feel like the example for “loading definitions” does, in fact, strike a word from my vocabulary without suitable replacement. I would like a word for “the aspects of masculinity that are bad”; in order to prevent the conversation turning into a bunch of complaints about my use of a particular term, I instead have to just say “masculinity.” I do not want to use “masculinity” to mean “the aspects of masculinity that are bad.” I would like to distinguish between those two things.
(While I have no moderation power, I would personally really prefer that this conversation not turn into a conversation about the merits of that particular term.)
One polite way to respond to people using words you prefer they not use is “[Word] upsets me for [Reason], can you use [Replacement Word] instead?” If they can’t (because they’re not a native English speaker, or they have a linguistic disability, or they are chronically sleep deprived, to name just three of the reasons that word replacement can be impossible), then you have to judge how important not being around people who use Word is for you.
You could also consider asking what they mean if you don’t know what they mean. My rough sense is something like “a cluster of chemicals the central examples of which require industrial manufacturing processes to create, did not exist before the 20th century, are not part of any culture’s traditional way of doing things, could not be manufactured in a home kitchen, and bear little resemblance to petroleum, corn, or soybeans in spite of being derived from them.”
