A political cartoon makes an obvious comment on the US House of Representatives passing a resolution condemning the Turkish genocide of Armenians.
The cartoon has a point. Our genocidal actions against Indians were much worse than the Turks' genocidal actions against Armenians. "Let he who is without sin cast the first stone" and all that.
But the cartoon overlooks a couple points:
1) The US government and many Americans have acknowledged our past crimes. True, some people are in denial about calling it genocide, but most people admit we were guilty of something. That's more than we hear most Turks saying.
2) As long as we're not in total denial about our own sins, there's nothing wrong with condemning the sins of others. We have every right and responsibility to tell the world about mass killings--whether they occurred in Rwanda, Sudan, the Balkans, Cambodia, Russia, Turkey, or the US. Helping people understand that genocide happened before and can happen again is one way to prevent it.
