Your whole post is completely empty of details, so how can we decide?
Are the disagreeable things disputes about some software thing? Or does this guy feel that homosexuals should die, that trans people are sick, and women inferior? Or something in between?

To be frank, I believe the reason that you don't even give a hint as to exactly what he's saying is because if you told the details, people would be disgusted.
RMS had a long history of saying annoying things about the computer industry, and that's a good thing - that's his job.
But when he started defending Jeffrey Epstein because one of the girls he trafficked was as old as 17 and had been pimped out to Marvin Minsky whom RMS admired!
A lot of people simply didn't want to be in the same room with him after that. "One of these girls was close to not being underage" is a terrible argument.
An example in my real life - a friend of mine called me up out of the blue during the pandemic and made a big play for the message, "There are too many old people on the planet, so many of them need to die."
I don't think she realized how old I was, but it makes no difference. We never really spoke again, because depraved indifference to others is horrifying.
