You could probably count me among those people too! I'm a lefty, but the same is true of the right.
I read the first post as a call-to-arms for the Republicans, and anything that would appeal to their prejudices was trotted out. Naturally, I found it distasteful, but nothing erquires refuting: that would dignify it far more than it deserves.
To me, Obama seems much more appealing than Palin. That's my point of view, since you ask, but I'd prefer a proper liberal, or even a social democrat.
