Ok... I thought I could do this purely because no one else has... I'm not even sure where to begin with this one...
To begin, the entire idea is based on an assumption (and you know what they say about that word). It's completely illogical to base an entire argument on something that you, without any prior solid information and proof, believe and assume is true. Assuming that capitalists are the carnivors and the communists are the herbivores is like saying that the sword in some sandwiches is to represent the victory accomplished that allowed you to buy said food and the umbrella in a drink is symbolic of the comfort that comes with being drunk (though this could very well be true for some people).
The next issue would be the context with Lenin's brother's death. According to his previous deduction, if his brother was killed by a capitalist, what he says is true. However, Lenin's brother would have been killed by Nicolas II. I'm not sure if this person understands politics or not but following a totalitarian rule is not the same thing as living in a capitalist world. Paying attention in history class will help ya there!
The Great Valley does in fact relate to an ideal. But so does almost every social convention in history. There have always been dreams of being able to reach a Utopian society. A world with no fear, hunger, or suffering? Isn't that a goal of capitalism itself? The "American dream" so to speak? Isn't that what Heaven is supposed to be?
This is followed by confirmation bias to an extreme! Look out! He's got a beard!! I didn't know that being old meant you were Karl Marx. Dang, there go my impressions of Dumbledoor or Santa Clause!
Ok, I admit, relating Sarah to the Menshevik party was creative. I just didn't know that she could ever eat meat! If she shares some of the capitalist qualities, wouldn't that make her an omnivore? Dang! There's a scary thought! Who'd wanna be eaten by a triceratops!?
Wait a minute! Ducky represents propaganda!? Where'd you hide your posters? And Pitri... poor Pitri... Apparently you're needed to "mold the masses"... I thought getting Spikes help was all Littlefoot's job.
And more confirmation bias, where is this person's proof that the size of the dinosaur represents the size of the populous that applies? And, even taking it as true, if this entire piece is written to boost communism, why make such tiny heros? And aren't we missing Chomper?? Where'd he go~!!
My last point from the piece would be if "they defeat the last carnivor" then in the next movie how is "capitalism a menace"? Aren't they all dead?
Finally, it was said already but I agree. Which side is he arguing? He starts by saying that Don Bluth is saying this, however, after a few paragraphs the writer forgets to mention this again (thus tying his thesis) and gets lost in his own word choice. By the end, this piece becomes like Stalin's history books. Is this person a capitalist or a communist?
Not that it matters though. In this day and age, do people really still fear an idea?
