The comment said "Islam", but you said "Muslims". There's a difference in this case. I think the meta point behind that comment is that cultures, philosophies, and religions need to excise harmful ideologies from themselves for human rights to progress.
Some forms of Christianity need to remove their hatred of gays or other races.
Some forms of American culture need to value non-American life more highly.
Some forms of Islam need to discard their love of theocracy, male superiority, and jihad.
Though you've probably heard plenty of Muslim bashing and "Christians vs. Muslims" idiocy, that's far from what's going on here in this discussion. It needs to be possible for us to separate people and ideas in our minds, so we can elevate people while dismissing the harmful ideas that motivate harmful behavior.
That's all fine and dandy but none of that nuance is in the comment you're defending so I'm not sure why you're trying to retcon it in now.
That's what made it so strikingly offensive: it's trying to portray 1.6 billion people in many countries around the world as a uniform group with a single belief.
