So, not at all, because li and ĝi already opportunely express what the non-esperanto pronoun ri wants to express.

But it's ok, I always say that you don't understand Esperanto, so it's totally normal you didn't catch that.

I don't understand why li it's valid for a totally non sexed, non gendered, non bodied beings like god (who indeed is minority in the universe and one could say it's a non-binary being) and angels but its not valid for people who don't want to be represented by the three (again, why "bi"(nary) when it should be "tri"(nary)) gender system.

You just invented that. The Esperanto grammar just don't say that; nowhere. And Zamenhof himself told that li can be used with people when you don't know their gender. The Universala Vortaro just translates to some languages, giving not definition of it, but, for example, the translation to french is "il" and "il" it's used in French for god, and the same for the English "he". And both cases are or was used (when UV was created), when the gender of a person is unknown.

And please, show me where I have insulted someone. Please. Maybe you felt insulted, but that wasn't my target, and it's your problem.
