If any of you read about the Warring States or the pugilist world in ancient China, you would probably know that politics and semi-religious ideologies are often the centre of their conflicts.
I would say that Falungong and CCP is just a modern version of such.
Most importantly, I think such an issue would boil down the simple human behaviour of pride, not wanting to admit their flaws in the systems they created. It simply stretched beyond the limit to give such a tension (pun unintended).
