We have he/she/it and they by default in Polish. But apart from some crazy kids no one is using "them" as a singular form and no one is using "it" towards humans... I mean unless you're making fun of em.

Systematically there's no push for this lunacy and generally if you write your papers using this "new speech", you will fail.

There was this case recently when some run from home, drug abusing, ultra liberal, non-binary girl claimed she was raped by policemen while being detained for stealing a bottle of vodka. She's using "it" as a pronoun and one liberal press outlet wrote the whole article about it using neutral words. So "she/he went" in Polish is "ona/on poszła/poszedł". For "it" it goes "ono poszło" and it sounds funny for us. Out of place, especially in context of people. That article became a laughingstock.
