In my opinion, 9/11 is not an appropriate topic for this blog but climate change is because climate change is intimately tied to fossil fuels.

Additionally, I didn't see where Professor Goose made you a moderator of TOD. Oh he didn't? Then why are you worrying your head about it? The editors and contributors of TOD will police it (or not) as they see fit.

Grey: Neither topic is appropriate here IMO but most 9/11 bloggers do specifically relate the events to fossil fuel depletion (necessitating Iraq oil grab).

I believe that you are flatly incorrect about climate change as there have been many main articles on TOD itself in the past on that very topic but none, ever, about 9/11 conspiracy theories. If Professor Goose has allowed articles about climate change here and if those articles have been posted (both of which are true) then discussion of climate change is part of this blog.
