It's well-known that CCP leaders are untouchable in China just like Kim is untouchable in NK.
On the other hand if you look a bit to our politics, how affected was Trump by the rape/harrasment accusations? Certainly a big part of population would still vote for him even if the rape would be recorded. I don't defend China or CCP but we should put things in perspective.
The most disturbing issue in China I believe is the censorship and persecution of the victims.
