I haven't really seen much side-taking on the forums, which I consider to be a good thing. I don't really think there's any call for it. But sometimes it's not about sticking up for someone or choosing sides, just a matter of wanting everybody to be understood.
Ted: I don't like cardboard boxes. I opened one once and it was full of foam peanuts. I have no use for foam peanuts.
Tom: Did you dig around in them a little?
Ted: Of course not. What do I look like, an excitable house pet?
Tom is now confused about what house pets have to do with anything, and decides to abandon the conversation because Ted "isn't listening". I would probably say something like, "Ted, Tom meant that there could have been something else buried in the foam peanuts, which you would have found if you rooted around in them a little." I'm not taking Tom's side, but I hate misunderstandings, misinformation, and the like.
