Your argument comes down to this: people should not be reminded that war is hell. That's it. That's the entire crux if your poorly considered post.
If you're a pro-war sociopath, then you have a point. If you prefer a well-informed populace, then you have no point at all.
Worse than that, you're attacking people who can add additional perspective solely because they're not providing every perspective simultaneously. It is morally disgusting that you claim The Guardian damaged the search for truth by adding counterpoint to existing propaganda efforts.
It is truly sad that you felt the need to attack The Guardian for writing this. You are eloquent, but deeply misguided.
