Let's try that again by removing the word "stupid".
Here's the report.
Here's the closed thread.
Now -
As you can read in the report, most people of both camps believe that we should not have invaded Iraq if Iraq had no WMDs or strong connections to Al Qaeda. And as it turns out, most Bush supporters support the invasion of Iraq. And as it turns out, Iraq had no WMDs or significant methods of obtaining them and no strong connections to Al Qaeda.
But most Bush supporters do not believe the reality.
Are they intentionally ignorant - meaning, they know that the reality differs from their belief in some way, but they are not going to adjust their belief to match reality ... or are they lacking in the mental capability to recognize that their belief differs from reality?
And I would note that, although this is unflattering to Bush supporters who do not believe in reality, that is no excuse to consider it trolling.
