This seems like a red herring to me. Fine, IRC gives you the same kind of socialization opportunities that most people can get in meatspace, which you can't get there, and so losing it would be particularly painful. But nobody is suggesting that you should lose it that I've seen; all you're being asked to do is apply the same sorts of filters that people are expected to apply in any public social situation, or as pragmatist said, "any public forum".
