Are you saying that, since people take this seriously/personally (they don't have a monopoly on seriousness - I take it seriously too), inquiry into what exactly happened is for some reason off limits?
I'm afraid that is how it often works.... I certainly don't like it, but I see no real way to change it short of somehow altering all of American culture and society.... generally when a lot of people die in something like this, a lot of other people REALLY don't want to hear about irregularities in the way the collapse happens, and will flame and rant to keep it off the boards. Since you can't change the people, oftentimes it's just easier to move elsewhere where this sort of thing is "on topic" and the ranters are to be expected and thus ignored. I rather like my fur coat at a PETA rally analogy from before: the guy in the fur coat really isn't doing anything wrong, but is simply wandering into a situation that can only end badly, and thus probably shouldn't do so.
I really do think that "off topic" is a bit of a misnomer for this section of the forums... it is really meant for things related directly to the nerd/gamer community, not politics or current/historical events.
While I certainly agree that "trolling" has become an over-used term for random people whose ideologies other people don't agree with (heck, some guy called me a troll once for coming out in opposition to MARTIAL LAW!), I try to be fairly specific about where I use the term. Note that I said I only SUSPECTED you of trolling (and even then I said that if you were, you would have to be REALLY good at seeming like an honest poster), a suspicion I no longer have.
