So is it just me or do the Dinobots on Transformers teach kids that its okay to discriminate against the mentally challenged?
The Dinobots are a small group of Transformers created on Earth by the scientist Wheeljack. They are the first attempt by the Autobots to create new Transformers since fleeing Cybertron. Since the Autobots lacked all of the high-tech resources they had on Cybertron, the Dinobots turn out to be less than perfect creations. In fact, they seem to be functionally retarded. They can only speak in broken English, have poor motor skills, and are unable to grasp all but the simplest of concepts. (Note that the cartoon show departed from the characterization established by the comic books on this point. There, the Dinobots are extremely intelligent and gifted warriors.)
Having created their own "special" children, how do the Autobots react? With ridicule and disdain. The Dinobots are the constant the butt of the other Autobots' jokes. When "raising" the Dinobots proves too hard, the Autobots send the Dinobots to their own "special" island. In the Transformers movie, when the Autobots are forced to retreat from a battle, the Dinobots are placed in a separate ship from the normal fully functional Autobots.
What makes this harsh treatment worse is that the Autobots are the source of the Dinobots disability. While in real life there are many factors that can cause cognitive disabilities in children, the Autobots knew they were making mentally disabled "children," and yet they continue to ridicule their poor creations.
So when little Billy makes fun of the "weird kid" on the bus, maybe this is where he got it from. Or I could just be reading too much into that ...
