They don't know a shit about hedonism. Epicurus, the first who talked about "hedon" described hedon as a state of no disturbance, no pain and spiritual calmness.

Communism, another rejectable western child, rejects the theological and supernatural matter of religions and view them as cultural elements of the past, mostly ethical rule over society. Viewing them as such, a reasonable person if he sees elements of oldschool ethics compatible, applicable, and generally good, why not embrace them? That's the long story short about socialism with Chinese characteristics
