I'm pleased to say that so far, even though there are people from all parts of the political spectrum leaving comments, I have not yet had to worry about a comments policy.
Besides obvious spam, I have only deleted one comment since I started, though I have been strongly tempted on two other occasions. I would be very happy if I never had to delete another, though I will not hesitate to do so if necessary. But I'd rather not be in the uncomfortable position of deciding what does and does not cross some line.
All views are welcome here, those contrary to my own included, and I hope respectful, but hard fought and intelligent discussions over economic and political issues continues. Or, you can always say something nice. Leaving comments is scary for some people so that's appreciated too.
Just wanted to say thanks.
