Presumably this refers to his peculiar set of neologisms (“per” and “pers”) as a gender-neutral pronouns.[1]

Stallman is an extremely stubborn language hyper-pedantic with some fairly unconventional views and usages on any issue, not just this one. And he has 20 years of documented support for trans people. So with that context in mind, I think it makes sense to take it in good faith.

To say I find his position on this peculiar would be an understatement. But I find that on many of Stallman's positions on similar topics wrt. language. Either way, I'm reasonably confident it's not intended as a cover for transphobic bullying or the like, even though it may appear like that at a glance.
