This raises the question, do some Klingons use bIH for humans and other races that don’t speak Klingon, even though, nominally, Class 1 is for all language-users. e.g. calling humans “tera’nganmey”.
On another note, I wonder if some Klingons refer to slaves using Class 2.
There’s a lot of room for cultural interpretation in this language. :D
Klingons tend to be more scientific than political regarding grammar. Though humans may have trouble with Klingon, they clearly fully use language and qualify for that class. However, I won't go so far as to say that no Klingon ever used the wrong class in order to try to imply something through intentional misuse of the language.
Computers are fancy machines capable of imitating speech. I think trying to say they are beings capable of speech would be the more political view. The Klingons seem to think it's less political, but the Federation sure seems to treat it like a big deal. No wonder the alliances keep falling through.
