- RMS's main reason for introducing "per, pers, ..." was to use them in written English; this was just his own weird solution to a problem that a lot of people have noticed in modern English, the lack of a good singular pronoun for "a person" in general, without referring to anyone in particular. Lots of people have come up with crazy ideas for this, not many people are passionate enough about their use of language to write long blog posts about them, but, well, rms isn't everyone.
- Using people's preferred names is a matter of common courtesy, and this has been the case pretty much for all time. People having preferred pronouns, in contrast, is relatively new, and even 50 years ago nobody would have been familiar with this idea. It would be charitable to not judge an older generation by the standards of the young when something is changing even within our lifetimes.
- Insisting on using only full names would be bizarre, but surely nobody would take that as a personal attack, because presumably nobody would feel "singled out" by this. I think if you want to know if RMS was trying to antagonize non-binary folks or if he was rather just being prickly and a little eccentric about language, you would need to look further than this one idea of his. As far as I know, he is rather progressive on these issues, and he also has a history of passionately advocating unusual word choices, almost none of which have caught on, so I would lean towards this being just another example of his eccentric opinions about language, rather than trying to antagonize anyone.
People having preferred pronouns is a new idea in most English speaking cultures because intersex, transgender, and nonbinary identities are new ideas in most English speaking cultures. Stallman doesn't use an older generation's standard. He says we should respect other people's gender identities by using the appropriate pronouns.[1]
Many people felt singled out when Facebook insisted on full and legal names, for what it's worth.[2]

The first sentence of this thread: "Dude has gone out of his way to make other people uncomfortable."
I'm simply saying that, on the basis of your [1] alone, I would not come to that interpretation.
Undoubtedly a weird, outsider view of things but I wouldn't advocate him being punished for doing so. Nor would I advocate for shaming him for choosing to use people's full names in daily conversation.
The same reason we use people's names. Or their nicknames. Or their middle names sometimes. Or their stage names, noms de plume, or noms de guerre. When you are introduced to someone you expect to be spending some time around, you might ask them, "Do you prefer Henry or Hank? Charles or Chuck? William or Bill?" And if they say, "Actually, I use my middle name, David." you wouldn't immediately say, "I'll go ahead and use your full first name because it's an equally equivalent name for you, because I'm respecting the concept of you.
Culturally, we already accept a wide variety of markers for people in a host of different situations, and have generally settled on "it's polite to try and refer to people in the way they prefer."
To me, it's as if RMS had posted a blog post that said, "I propose we use only people's full and legal names when referring to them, because I believe that system works better."
