You're pointing out the obvious then, Which Im sure most gaffers of age are aware of. Like I said earlier, you are just going over the history of known effigies and political strategy.

No, you're not saying much which is why I have to keep probing to find the meaning behind posts of images. I'm glad we are both aware that its racism at its finest, and that it is separate, and has no relation to the bush imagery in those specific terms.
I know I'm not saying much, which is why it shouldn't be too controversial. But I am saying it for a reason, so perhaps I should just make it explicit...
Playing "my guy got it worse" inherently drives a divide in the discussion. We should all be able to denounce hanging Obama and Bush in effigy, we should all be able to denounce the corruption of Rep. William Jefferson and Rep. Tom DeLay, we should all be able to denounce the violence done in the name of the Animal Liberation Front and the Army of God. But as soon as it becomes an "us" vs. "them" debate, justified or not, there's no hope of rational discussion.
What we should do is say, "Yes, it was inappropriate for GWB to be hanged in effigy, just as it is for Obama to be hanged in effigy, and neither has any place in American political discourse." (And it's not an attack on freedom of speech to attack such speech with counter speech.)
