In my opinion, China may already collapse without Deng and his folks.
Without Mao, China may not be as strong as now. So I don't totally disgree with you.
But many people should not suffer that much without Mao. A strong China is what we want. A China that people can happily live there is also important. So our goal is the same. Our difference is only: you like Mao and I like Deng.
So we don't have to argue too much.
