> "smell test"

There are a lot more people who would fail that test and be offended when pointed out. That group includes some forms of mental illness as well.

Don't people who "fail a smell test" and get offended do so because they they think it's a propestourous claim they're failing it? It's kind of the opposite situation, cause wouldn't that make them not take it on themselves by default and thus not wish for the nonuse of this phrasing?

Are we just disregarding the differently-abled people who have a diminished sense of smell? /s
