Do you think the government was involved in 9/11, and has successfully covered up their involvement?
Um, no. You said the following (and I'll admit I didn't read the rest of your post initially):
The US is not immune to evil. But there is no credible evidence that the US purposefully had anything to do with 9/11.
If your argument is that the government could have done things to prevent it, that’s not “truther”, that’s just the truth, but is beside the point.
You treated what was, IMHO, a wacko "truther" post, with dignity and seriousness and answered in your classic and somewhat pompous way, giving the post (which a lot of people are still WAITING for an answer to) credibility (and plausible deniability)!!!
Okay, I'm better now. I'll let of few others weigh in on whether I'm off base or not. I'm willing to be told I'm wrong.
