I don't think there really needs to be a rule against changing the topic. Chats aren't blog discussions. In a chat, just as in a face-to-face conversation, it's perfectly normal for the topic to change, sometimes abruptly, especially when a new person joins the conversation.

As for offensive comments, there's no right to not be offended, precisely because offensiveness is in the eye of the beholder. Ditto with mean-spiritedness. There are all too many people in the world who honestly believe that anyone who disagrees with them is automatically mean-spirited or worse, especially when the conversation turns to politics. If it becomes clear that somebody is flaming for its own sake, then that's another matter.
