It's not a good idea to start out a statement with "I don't know".
I think if you've watched this guy a few times you'd understand his motivations.
Regardless the question remains: does calling those that die in battle encourage anyone to die in battle? Or worse, does it encourage anyone to create wars for the purpose of allowing people to die a "glorious" death?
Historically, I think there is evidence that this might have been the case (see almost every British-lead battle during WW I).
Best way to prevent war is be in one and see it first-hand.
Again: Not the issue.
Given that many have not been in combat, and never will, (not to mention the complete impracticality of your point) does calling those who die in combat "Heros" do more to encourage or discourage war?
The fact is IT ENCOURAGES WAR.
Next question is: Is War entirely bad?
Answer: No. Fuck Chris Hayes with a 12 inch dildo if he believes there is nothing good about the outcome of war.
