What would you reply to this:

Quote by me: But if you're not politically involved, how are you so sure that you're not being deceived?

How would you reply to this:

"1. Because they fully denied it.

2. Because we've had hundreds of experts in the fields of politics, engineering, and aviation that said everything pointed to a plane hijacked by terrorists crashing into the WTC and Pentagon, bringing down the twin towers and WTC 7.

3. Because terrorists have claimed the attacks as their doing

4. Because the US government has little good reason to have committed the attack, who's planning naturally would have had to occurred long before George Bush swept the political stage with his nationalist and aggressive foreign policies.

5. Because not a single person has come forward and given us hard firsthand evidence that it was actually an inside job. And all that exists is speculation and a very fringe group of scientists that are mostly being led by their own ideas before their science, very similar to Global Warming sceptics.

6. The economics don't work. Any idiot could see that a very expensive and hushed up operation on top of what's now trillions of dollars out of operation within Afghanistan and Iraq vastly outweighs any benefits that could come out of it. You say they wanted oil? Afghanistan has negligible oil reserves, while the invasion of Iraq has brought little new oil into US pockets, surely not over a trillion dollar's worth. So the only explanation is that hundreds of organizing bureaucrats are just evil, willing to murder their own people for at most trivial gains at the least absolutely no logical gain whatsoever.
You may be tempted to bring up Nazi Germany or Soviet Russia, but that comparison would be false. In both cases, the public knew fully well who was behind the abductions and displacement and murders, the leaders of whom paraded out in full colours:
In the Nazi mindset, Jews, Roma, homosexuals and disabled people were not fit to live on the earth and had to be purged from society.
In Soviet Russia, the starvation of millions was a necessary evil to keep the country's economy moving strong.
In the US, the outright murder of 3000 random US citizens was essential in... well nothing really. They got some extra international wiggle room that has given them no new standing on the international stage (less, even,) has brought some important sectors of their economy, notably Airlines, to far higher levels of inefficiency, and lost them trillions of dollars in wars they were catapulted into after the attacks.

I'd go on, but I'd think that's enough. "

A simple response to this would even be nice! thanks!
