Racism vs Propaganda vs War vs Evil
Okay, here's how it works people. Things can be evil, yet have a unavoidable purpose in certain circumstances. For simplicity's sake, let's define "evil" as an action that should NEVER be performed against your fellow man for whatever ethical or moral reason you choose to select.
Racism is evil and so is murder.
During war, (which is also evil by the way, but it happens anyway, the reasons for which is an entirely different discussion) we use racism and murder as some of the the tools to achieve a war's goals. Yes, we cloak the racism in the banner of "patriotism", and murder in the guise of "killing solders", but in the real world, the act is what counts, and our nomenclature does not change the reality.
So racism and murder are both STILL EVIL even in the context of war, but are unavoidable tools of war. Their "evilness" has NOT changed, we have simply entered into circumstances that demand their use - evil or not.
So guess what - a movie that portrays racism and murder is still portraying EVIL things - sorry war fans. BUT, war does demand the use of both in some circumstances - sorry pacifists. But war is evil in itself, so that doesn't justify the racism or the murder themselves, just the context in which they occur, IF there is an overwhelming reason for the war.
So you can be FOR a certain war and AGAINST racism and murder in general, or you can be AGAINST racism, murder, AND war for the trifecta. (Or I suppose you could be FOR racism and murder and against war, but that makes you a freak and you're not invited to my house for Thanksgiving, thank you very much!)
The trouble is, war is not neat and clean, and it's hard to hold back falling bombs with your principles. Yet, war is also not "inevitable" in many cases where it has been inititated - so much racism and murder occurs in the context of wars that should NOT have started in the first place.
Summary: Racism, Murder, War = Evil. But if you decide to have a war, it's hard to prosecute it without hurting feelings, killing people, and destroying property. That's the reason to avoid war in the first place.
Simple.
