I could be misreading you but my general sense is that you tend to be antagonistic in sometimes underhanded way, like above - you lifted that part from a sentence which was listing two examples prior to that phrase. That's an disingenious way to discuss regardless of the topic. To put in your way, I find your way of communication failing to meet my standard for productive discussions. I've given brief reasons why I don't think it fits. If anyone else wants to discuss that further, please raise it. I'd be happy to discuss. Paolo, if I'm misunderstanding you, my aplogies but otherwise please do better. Thanks. -- tejun
