MIT is consistently rated as the best university in the entire world and produces students and pieces of research that are consistently changing the world's progression in all areas of scientific research. Since the serious academic rigour of MIT can't reasonably be impugned, the students shouldn't be prevented from taking a lighthearted approach to their studies from time to time.
These classes are fun and are about physical education. There are a wide variety of classes that a school might offer and it does not make sense to pass judgement on the insutiton for offering them. Students need a break from the seriousiousness and the instense educational rigor that MIT creates and this is a great bit of fun.
Yes, a higher education institution should offer these courses because it shows a wide range of thought. Students should not simply take the basic courses that are offered in high school. They should be able to experiment with other ideas and pursue their passions. College should offer every possible course.
Higher education is not a joke, it is a serious element of modern society. To deem students "Pirates" after taking certain courses is either to condone the illegal behavior of pirates or to treat as a joke the important business of educating students and teaching them to behave in a responsible way in society. It is not the courses that are at fault, it is the certification of "Pirate."
