I disagree. There is no correlation between "real progress" and "not upsetting people".
There is clear, documented evidence that toxic teams and cultures are less productive than teams with high diversity that listen to each other and are safe to express opinions in. I would link it but you're probably not going to read it or listen to anyone else's opinions so you can google it yourself.
It's Tragedy of Commons stuff: there are marginal benefits to the individual of behaving like an asshole, but the group suffers.
I'd be interested in reading about that. A brief search yielded research about effects of diversity on team performance, but I couldn't find articles on toxic or hostile cultures.
