Most wrong-headed article in quite a while. Hitler may have hated snipers when he was in the trenches (as other soldiers did), but his army certainly made use of them. Total war means making use of whatever tactics commanders think will win (or hurt the other side).
Was William Tell really a sniper? Hitler is supposed to have exclaimed in 1942: "Why did Schiller have to immortalize that Swiss sniper!" But his plans for last ditch resistance in 1945 included heavy reliance on snipers. He certainly didn't have a principled opposition to that tactic or any other that served his purpose.
You completely missed the point. Hitler hated snipers that were aiming at him which is why he hid in a bunker for most of the war. Why else do you think he banned Schiller's play about William Tell? He was afraid someone would be inspired to shoot him like the hero of the story.
