This invitation applies in particular to those who say things like, "Just because you disagree with them on politics doesn't mean you shouldn't respect them." This line of argument pisses me off. I may not express my disagreement with the same vitriol as Caitlin Johnstone, e.g., but I understand where that vitriol comes from.
There is a difference between disagreeing on political matters, on the one hand, and perceiving the other person or party as culpable in mass slaughter of civilians in shelters and troops in retreat, on the other.
The mere act of dying does not absolve Bush of his crimes, any more than it did Jeffrey Dahmer or Timothy McVeigh. You may call it "shitting on his legacy," but I call it honesty.
