full of reactionaries shitting on Linux for having a CoC and enforcing it.

Because they don't enforce it for Linus. Yea he "took a break" and went to therapy etc. (before the CoC was introduced IIRC), but he still routinely abuses people publicly with no remorse or empathy, and continues to do it for decades now. As another commenter said of the CoC and Linus's continued current behavior today, "Of the 10 bullet points there he violates 6 of them."

And I don't agree with the people who claim "he has to be that way because blah blah and Linux wouldn't be what it is today etc.", I still think it's entirely possible to be a whole lot nicer while also being firm when necessary and still achieve the same end result.

Of course people are upset over double standards.
