@scrumpy: Apparently you have never had the misfortune to deal with someone who wants you to do their work for them. When "civility" fails it's time to break out "subtle". When "subtle" fails it's time to break out "blunt". I can't say what follows "blunt" because I'm sure the censors wouldn't allow it.
People you have no patients for... I've got lots of those. Civility who needs it? I don't care if I end out with -100 votes down, the only person who really matters to me... is me... and my family.
