And to other's that seems like he doesn't respect the wishes of others and instead behaves in a way that is logically sound in his own mind. That's not a crime. Just a disrespectful way of behaving that generates antagonists instead of friends.
Side note: "per" is very funny to me as a swede since it's a super common traditionally(exclusively?) male name.
Please define "others". It should be a definition that is not only "transgender people". Could it be "all the people in the world that is not you"?
If so, it is impossible to please them all. Some will contradict each other. It will generate antagonists or you will be seen as rude whenever you want it or not.
So you may decide you will be siding and pleasing those "others" who are "right" (based on your personal preference only). But at the same time, not everyone who is "not right" is necessarily "wrong".
I'm not siding with anyone, and I won't tell if I use or not special pronouns. But today the discussion is about pronouns. Tomorrow, who knows? Up to where are you willing to bend?
That goes both ways though.
This seems acceptable to me. Stallman has always been weird with word choice but I see no bad intent here.
