Well, at least you're elevating the converastion. I don't know why people feel so compelled to bash people. Whether it's Bush, Palin, Bill Clinton or Obama. Pig headed? Really? Okay, but we'll never advance as a society with that, in my humble opinion. Just don't see how that elevates us at all. It might make people even stand stronger to 'their side' and fight harder against 'your side', no matter what is truly right or wrong or which way is better. But keep it up.
Maybe in 20 years some will still be blaming Bush and calling him names. But just know, the same people you're chastising for blasting Obama, perhaps erroneously, are just the polar oppostite of you. So if you really think it's a bad idea, you might think about changing yourself first.
