There are usually all kinds of twists and turns in a HN discussion. And it's not like we're discussing the background colour or something far off-topic, the title is a pretty noticeable part of the article. I don't think it should be verboten to discuss these things.
I agree that transgressive speech is an important tool, and tone policing is generally bad news.
To each their own.
I find it hard believe that any discussion like this is genuine and I am deeply suspicious of people that complain about hyperbolic and provocative language.
Moreover, I think complaining about it like people have is here is verging on being ridiculous tbh.
Again if I didn't know better (i.e. I don't think this is happen) I would actually think it deliberate to run interference.
