I mean, it is a difference of opinion, that is factually true. But, by the same token, Hitler also had "different viewpoints" on Jews and minorities.
Just because it's a different opinion doesn't mean it's something that should be accepted or tolerated.
Kill 1 man: You are a murderer. Kill 10 men: You are a monster.
Kill 100 men: You are a hero. Kill 10,000 men, you are a conqueror!
