It's not independent, you can't just drop the context. RMS the 9-5 software dev at some nameless corporation having this discussion is, while still unacceptable (because the relevant society has decided that it is obvious why sex with minors is harmful), not nearly as impactful as RMS the respected-by-many leader of the free software movement. The clout he has from that position and work makes him influential even outside of the sphere, as well as affecting people who might join the movement but are pushed away because they find his other opinions unacceptable.
That's why we're talking about it in this comment thread instead of ignoring it like we do most of the weird takes on the internet.
> I'm also not sure why "inclusive" is a good criterion for FSF leader, it seems like just a hollow shibboleth buzzword at this point. People who harp on "inclusion" are usually the most interested in exclusion.
The paradox of tolerance explains why it might feel like being inclusive of many groups of people involves exclusion.
