I've been having a very heated discussion about this exact topic with my stepfather via Facebook. There's a post circulating on the social networking site that reads as follows:
Time for a vent: A video is going around of Marines peeing on some dead terrorist. These terrorist will bomb, behead, kill without a care and rip the fabric of America and hate us at all levels. Yet people are in a uproar and demanding a investigation into it and want them punished? Marines trained to kill, did their job protecting the US from the enemy and acted like Men at War. They were dead and not getting any deader and deserved to be pissed on for wanting to destroy America. They want a investigation to punish? I want a investigation so they have be given a ticker tape parade as Heros, How many medals can we give them? Say thank you for supporting and defending America. If this offends you, decide if you like living in America and know that having freedom some times come with blood Ours and the enemy. If you like it repost

To which my response was:
How is pissing on and defiling a corpse defending America? If anything it furthers the "ugly American" stereotype. These marines should rightfully be courtmarshalled for conduct unbecoming of a United States Marine. Are they under a lot of stress? Yes. Are they in a war zone? Yes. What proof do we have that the deceased was a terrorist? How do we know that these men weren't doing this despicable act to an innocent civilian? Not every citizen of Iraq or Afghanistan is a terrorist. Terrorists, in fact, make up a very small portion of the citizens of these countries because they are extremist factions. How would we like it if the entire world looked at what these Marines, or the men and women responsible for the alleged waterboarding torture at Gitmo and thought that all Americans were as amoral as these people seem to be? No corpse, terrorist or not, should be defiled. By Christian standards, it's wrong. By Pagan/Wiccan standards, it's wrong. By Islam standards, it's wrong. By standards of DECENCY it's wrong. And by the standards of the Uniform Code of Military Justice which these Marines are expected to uphold, it's wrong. I'm sorry, but they SHOULD be punished, if nothing else, then for libel against the United States.
