From what I remember they plainly called him anti trans or transphobic because he suggested something different than they/them during a default pronouns discussion way back when this was all rather new.
A curious statement given his track record.
I also remember him being called a creep because he used to sleep in his office.
And at no point was any kind of change of opinion and/or public apology even hinted at.
He was advocating for "perse" (as in "person"), which is genius because there's no they/them for "Hello, sir/ma'am". If someone's gender is ambiguous, you're fucked. But you could say, "Hello, perse".
If you want to help your argument, especially since you're looking for an honest attempt at something, it's best to go by facts rather than memories. Another step that could strengthen your argument would be to define who is calling RMS anti-trans.
This is especially important, as time moves forward and people who never even met RMS read about this, to make sure we are relying on contemporary reports and not just fading memories.

It didn't feel like an honest attempt at all.
