Some people seem to want to use #contentWarnings for everything, I.e. as content headers instead, and others seem annoyed by that practice.

I'm trying to fit in with whatever culture was supposedly here before I arrived but there doesn't seem to be a consensus on what that culture was so

I think I'll just stick to using content warnings as warnings instead of headers. If you want them to be used as headers, get them renamed to something that doesn't have the word "warning" in it.
