It's true, not every language goes all-in on functional programming — but just because some functional languages are less strongly functional than others, that doesn't mean it makes sense to call every language currently in use a functional language. I mean, it seems pretty useless to define "functional programming language" in a way that includes both C and OCaml just because you can pass functions around in both of them.
