There's another type of believer. Those military vets who answered the call to join as part of the "war on terror". I lived with one. Navy. EOD. On one hand he knows the bullshit orders he got while in Iraq. If they found a house full of explosives and arms they were told not to blow it up, just leave it. The bureaucracy and the red tape made him retire. Now he fully believes the towers were taken down by a goat herder from a cave and there were weapons of mass destruction everywhere we just didn't find em'. No matter what evidence I bring up nothing registers. Truly brainwashed.
