I knew that would be your answer, I just wanted to confirm it. You are a man who has very strong opinions but doesn't have good reasons for having them. Many of us have spent years researching these issues so encountering people like you is very familiar. You are simply wrong about 9-11, Sandy Hook, and probably most everything in your mental landscape. But there's absolutely no point in going into the details because your mind is made up before you know the first new thing about them.
You are either lazy, as in "I wouldn't want to have to rearrange my whole belief system to let this startling new information in, so I won't." Or you are arrogant, as in "If there WERE such huge conspiracies then someone of my intellect would surely have figured it out." Given the high opinion you've expressed of your mental faculties I'd say it's the latter.
I'd be willing to bet you are a software engineer.
LOL no, I am not a software engineer. Do you realize that every single thing you just said about me could just as easily be applied to yourself? It is only because you are biased by being you that you accept your "mental landscape" as the correct one.
If you were me, then you would see things from my point of view and it wouldn't feel "wrong" because you'd be me and I don't think my point of view is wrong. I do however believe in common sense, the scientific method and a tangible, objective reality, three core criteria frequently bypassed by conspiracy addicts in search of their "truth."
