If people buy that crap then they probably deserve to be duped. I don't know, maybe it's because members of my family were very closely tied to the events of 9/11 that I find it offensive that there are those that want to belittle all the efforts to recover from that by accusing many of those same people with plotting the whole thing through a conspiracy.
Even more so, I think it's regrettable, to say the least, that the direct victims have to suffer the indignity of being part of these ridiculous claims.
