Murderbot gender rant

Argh! So fed up of people misgendering Murderbot! So fed up in fact that I just left a long comment on a YouTube video to that effect. The guy had done a long video enthusing about how great the Murderbot diaries were - which was great - but calling MB 'he' throughout. And clearly someone had challenged him on it before because he had a bit about how it was agender and he knew of a lot of people who called it 'she' because they identified with it more that way.

Meanwhile I'm like "It calls itself 'it'! It calls itself 'it' consistently throughout every single book, so what about that indicates that its pronouns are anything other than 'it'?

Why do so many people see a character who is vocal about having no gender and no sexuality, and who calls itself 'it' through five different books, and think "oh, clearly I can call this character 'him' or 'her' or even 'they' according to my whim?"

I'm just like, what kind of reading comprehension do you have if you ignore every single time the character is referred to throughout its own series, in favour of choosing a pronoun to suit yourself? What kind of entitlement? As a fellow agender person it absolutely infuriates me.
