It's a distinction without a difference. Sure, they're well-meaning. They don't know they're working for the destruction of America. They just are. Their good intentions don't change the facts of the matter.
If I point my gun at your head, and shoot and kill you, I'll be charged with murder. If I carelessly spin my gun on its trigger and shoot you in the head and kill you, I'll be charged with manslaughter. The DA isn't going to let me walk because I was stupid.
I don't think these folks are simply being stupid, though. They're trying to rush legislation through before the public has a chance to digest what's going on. They've all read the history of our country, including the history of the Great Depression and its causes, yet they're pursuing the same policies that caused the Depression.
They can't be so stupid as to believe that their health care "reform" plan will allow for private insurance companies to compete with a taxpayer-funded system. They surely know that they're going to drive insurance companies out of business, and Americans will be stuck with the system the politicians devise. They know that they can't sell a single payer system, so they try to hoodwink the public into thinking that a government-funded program can coexist with private companies.
Even where their policies are the product of stupidity, it's the equivalent of multiple DUI's, and they should be imprisoned for Governing While Intoxicated with Power.
