This isn't "one-upmanship" Joe
One tragedy doesn't outweigh another, but to claim ove as "an act of Infamy" and to ignore the generations-lasting consequences of another is hypocritical.
Why not just describe them all as "Acts of Evil" and work towards making sure that they don't happen again?
As your comments indicate these "Acts of Infamy" have been happening for many centuries - wasn't America built on such acts as 'Sand Creek' and Wounded Knee' - and didn't the continue to happen right through to Me Lai.
Why not call all these things what they are - "acts of gross inhumanity" and stop discriminating between one and the other?
