The rebellion against the oppressive regime? That one?

Right! "The way of the great peace." Peace for us, step 1: violently overthrow the corrupt ruling class. Not that I'm disagreeing, that's an example of someone preaching peace and finding that it doesn't exist without standing for the people, and protecting them from oppression means killing those that are doing the oppressing (Ed Sheeran in shame), we're just putting that in a book and calling it a religion.

To be fair, in China through these ~500 years, every current of thought or philosophy was called a religion, and the line between religion, politics, and philosophy, was pretty much nonexistent. If someone had an idea and put it in a book so others can think about it, that was a religion. It's a bit weird for us today to read "legalism is considered a religion? and legalism is... Absolute administrative power, everyone is equal under the rule of law? Sounds familiar... Oh, there you go, the ruler writes whatever he wants and then kills whoever he wants by designating them as enemies. Like those dummy thinkers and book-writers." "all right, fine, let's look at Mohism: egalitarian society and universal love, cool! First paragraph on Wikipedia: paramilitaries-- oh."
