All of the following names are made up.
I'm facebook friends with John. We went to college together, and have since seen each other at reunions etc. We were never close, but get along well enough. I am a casual acquaintance of Susan, who also went to college with us, but am not actually facebook friends with her.
John recently posted an article on his facebook wall which sparked a debate with Susan. After a heated back and forth, Susan added several points to her argument and invited John to unfriend her. John addresses her points but did not unfriend her. The back and forth continued. Finally, Susan posts that she feels like John is trying to intimidate her into agreeing with him and basically says shes done.
John then starts a separate post stating that Susan unfriended him over the argument on his wall and that he doesn't understand why. He asks if anyone can take a look at the conversation and explain it, adding that he may try to follow up with Susan via email in a few days, but is afraid that she might take it as harassment.
In reply, most people are offering John support, saying that they didn't see any of John's arguments as offensive or overly aggressive, and some even adding that Susan had previously unfriended them over similar disagreements.
I don't want to get involved in this argument. However, I feel a little awkward about John publicizing that Susan unfriended him. Especially when they have a lot of mutual friends/acquaintances. My inclination is to stay quiet and stay out of it. There is however a small, nagging part of me that wants to email Susan and give her a heads up. Because if I unfriended someone and they started making it into a Thing, I'd like to know. But at the same time, I can't think of anything productive I would do with that knowledge. So tell me, ehell, is my first inclination correct? Ignore the drama and stay out of it?
In case it's relevant (although I don't think it is): I happen to agree with John's position, but I think that the article he presented was a horrible example and that Susan's criticisms of the article were reasonable and legitimate. In terms of the actual argument Susan started off very snarky and John responded in kind. But then the argument quickly transitioned to more of a debate than a snark fest, until Susan's final "goodbye cruel thread" post.
