Sorry, gang, but I have to start moderating comments again. Too many spammers and trolls are ruining it for everyone else.
Basically, your comment will get posted if you're on topic and have something interesting to say (btw, contradiction is not an argument unless you're backing it up; please take the time to make your case). I may not always respond to your comments, but I read every one.
My thanks go out to anyone who has ever contributed a comment to this site -- and I'm sorry that I have to start moderating again.
