So Buddhism is no less sectarian than any other religion that 's been round thousands of years. There are innumerable Mahayana traditions but they are all supposed to be grouped under the "Great Vehicle" banner. Contrast with Theravada which is about personal enlightenment. Both groups also draw from very different scriptures and apparently the goal of any Mahayanist practitioner is not just to achieve personal enlightenment but to become a Bodhisattva and help all others achieve it as well.
So, to very, VERY generally sum it up, Mahayana is a group tradition with the goal of helping everyone and Theravada is an individual tradition with the goal of self-liberation.
But why is this? Why couldn't a person just read whatever Mahayana scripture they prefer (and there are many with a lot of East Asian schools focusing their entire doctrine on just one or a handful) with the goal of liberating just themselves? I just don't see the need for this "everyone" vs. "personal" liberation where if you follow the former you read the Mahayana and if you follow the latter you read the Pali Canon.
