I can see your point. But if we are going meta... the discussion was going for quite some time exclusively between me and hef and though it got "heated" at one point, I didn't get the feeling that it was derailing at just some senseless uncivil exchange of insults. It is the kind of thing that can happen between a group of people talking at the bar, not just the internet.

Also, precisely due to this disconnect between what we write and how it can be perceived, it does seem helpful to me to occasionally have some curved ball thrown into the mix to help calibrate my sense of (a) where the other party is coming from and (b) check if the other party is willing to listen to you or just participate in a screaming match.
