It is even wider than that. I have noticed in my wider circle of friends. Deciding somebody is "bad" and ostracising them.

Often when people are at their most vulnerable and need to wrapped in love by their friends they get the opposite.

People kicking someone out of their immediate circle is not a new development. It always existed - both for good reasons and bad reasons.

It has become much more common in the last, say, 10 years, than it ever was. It used to be an extreme last resort, now people talk about it like it’s the obvious first step. Discussed previously: <https://news.ycombinator.com/item?id=32223003>

Hacker news thread is not exactly a sociological proof. In that thread, people talk in abstract and no one reading it has any way to figure out a.) what happened in anecdotes they talk about b.) whether such situations are more frequent then in the past. Besides, hacker news is a place where imaginary past gets written about all the time.

I was not trying to prove my assertion; I was just making an observation based on my personal experience.

I've noticed that the exact opposite is true - I've seen endless "one more chance" and "let's just bury the hatchet" for very bad behavior, behavior that should get someone ostracised.

People are extremely forgiving, to a fault, for those in their in-group.
