Why are people on here so uneducated about the war?

constant crap about our men and women killing for fun, killing for no reason, and basically portraying us as barbarians who and pillage. i have a cousin buried from afganistan, and another who lost his leg in iraq. i myself am enlisted to become a marine. im offended beyond comprehension by the accusation of my family and my friends to be barbaric and filled with a medival bloodlust. why dont people just research both sides to all arguements before they run that hole in their head?
