Well you can also have average Americans who think they have no business taking responsibility after it happens, since it wasn't something that concerned them, and nothing ends up done in response to it happening. Or you can note that some people did horrible things under the banner of your country and accept it as such, vowing to never let it happen again and holding those directly involved in the decision to account for what they did. Being upset that someone said "Americans committed war crimes in Iraq and calling it hate speech" is definitely not that.
