In general, I think this site is very well moderated. The moderators aren't really heavy handed at all, in my opinion. I'm no expert on moderating, but I did serve as a moderator for another forum for about 4 or 5 years, so I do have some experience. It is a very difficult job. It's kind of like refereeing, really, in that no matter how well you do it, somebody will think you either did too much or didn't do enough.
I agree with you that, in this case, the thread could probably be re-opened. I didn't see a lot in it that was veering too far into the political lane, if you will (see what I did there?).
"We are not provided with wisdom, we must discover it for ourselves, after a journey through the wilderness which no one else can take for us, an effort which no one can spare us, for our wisdom is the point of view from which we come at last to regard the world." --M. Proust
