With all respect for the opinion of the Guile maintainer (that is as valid as Stallmann one and any other person), I do not agree with the basic assumption here.
#FreeSoftware is NOT designed to "empower" anyone. Empowering people is a worth personal goal of the #Guile maintainer and many other FS #hacker, but it's NOT what qualify software as #free at least not through #CoC.
Well I also think that technology is a prosecution of Politics by other means so I support people who try to improve the world through technology (whatever for "improve" means to them, as long as "the world" is what they want to improve).
If you see a way software can improve the life of a weak minority feel free to code it! But the problem with SJW in Free Software is that they do not code to realize their vision, they try to bully others to join it.
I think that diversity in free software community is an important value, because different cultures might lead to different experiments and to learn different things, as there are different curiosities at work.
But such different explorations are often better served by hard forks, not by imposing to a community the culture of a subgroup (eg the US workplace hypocrisy, as CoCs do).
If you think a new Linux syscall might help, say, blinds, please code it!
