He is saying that War simulation games like Warfighter/COD/MW2 and so on could be construed as glorification of the subject matter, to some degree he is right if we use the same contextual basis as Jason2 and JSmoke. Clearly a game is just a game, whereas War is very real, but then for most people a soldier is no more a murderer nor is marking the passing of a Soldier no more a glorification of war than the Gamer playing Warfighter on his, or indeed, her PC.
If people such as Jason2 want to stand in personal judgement of what people like Chris Kyle and others have done then let them, I for one could not care less what they think or the ignorance they convey in making such judgements.
Disagree with the War by all means, but judging those tasked to fight on the ground personally is not really very helpful or necessary.
