I don't think the person getting flagged is always deserving of the dogpile. Your comment implies "you should take this time in timeout to think about your actions" which is just a gentler form of rhetorical struggle sessions, and not always warranted.

For sure. I've had comments flagged that I thought were perfectly reasonable and non-controversial. My first reaction was to be angry and annoyed. But then my kinder angels suggested that perhaps I phrased my idea poorly and people misunderstood that I was largely agreeing with them, or at least very respectfully disagreeing. And then I decided to be more careful with my phrasing next time.
