You know it is still possible to make a point and even to violently disagree with another's view - without making any personal comments about the poster you may disagree with or without conducting any public conversation about them. These are the sort of good manners that perhaps need a little more general encouragement online?

Online it is always possible to ignore anything you may not care for and to make no comment at all. This would not be thought of as bad manners and in this way other posters will have no choice but to respond in kind............

And for personal comments like 'me too' or 'well said' or 'bollocks' - that are of little or no public interest and only tend to ensure that there will be a public response in kind - members always have the option of PMs provided for very purpose of these personal exchanges.
