Putting aside your obviously strong beliefs against any kind of violence for a moment...
Actually it looks like geekmux held up games like Full Spectrum Warrior as examples of games that portray combat in a semi-realistic manner as well as demonstrate situations of justifiable violence. He also pointed to the American Revolution as a war instrumental in creating the most successful and prosperous nation in history and World War II as a war that was necessary to bring about an end to the barbarism of Hitler and concentration camps such as those at Auschwitz.
It seems to me that geekmux was effectively utilizing the subtle art of sarcasm to illustrate his points that many games are respectful of violent conflicts, the reasons behind them, and that sometimes wartime violence is an unfortunate, yet necessary path to travel to put an end to things like tyranny, torture and mass murder.
