I can't understand the argument that I shouldn't be upset with a human being because they're stupid, and make stupid decisions. Humans are capable of introspection, education, and change.
I don't think it's unreasonable to expect more of my fellow humans than of my cat.
But I guess I won't be mad at you.
So, I'm just making the point that frustration makes sense, but hate probably doesn't. They certainly aren't intending to be stupid, but it is frustrating that we can't show them the error of their reasoning sometimes.
