This issue seems murky. Peterson is fond of pointing to Facebook’s ’71 gender options’, but these are gender identities rather than pronouns. Either way, I’m sure I’m not alone in experiencing some cis bafflement at this. But so what? As a minimum, the neutral singular ‘they’ seems like an eminently reasonable addition to English (except, of course, it’s not an addition, but a long-standing, grammatically correct usage). And C-16 — with an apparent exception of inconsistency which I hope was tidied up — allows people to simply use someone’s name instead of their pronoun. (And again, it’s wrong to believe that the simple acting of using the wrong pronoun has been criminalised — it needs to be proven in court to have occurred in a quite extreme context of hate-mongering, or definite discrimination in the context of employment or housing, for example.)
