I really don't think many of those, like the poster you're quoting, are Americans. They may be in the US, but they are not Americans, several probably don't even live in the US.
I can understand the masses being spoon fed bullshit by the propaganda arm of the left, because most don't care enough to research or to understand how the people telling them the 'truth' on TV are compromised. But when you have people in here every day harping on the same things day after day, or defending what is happening to our country at the hands of the corrupt pieces of shit in DC, they are not you're average misinformed citizen. They are the enemy, and are purposely posing as Americans with opinions that are completely un-American. I don't even bother to read any of their posts, it's not worth the time.
