> Well I remember being taught about the Kent State massacre in school and how it was a stain on our country, and that we were learning about it because things like that need to be remembered, not forgotten.
School taught you the wrong lesson about it. ~Half the country (guess which half) supported it... And I've no doubt that they'd do so again.
What specifically is the wrong lesson that you've inferred school taught the original commenter about it? Correct me if I'm wrong, but it sounds like you agree that it was "a stain on our country" and that it needs to be remembered.
There are alternative stories about how the students attacked the soldiers who fired in self defense.
