I'm certainly not making a statement about Huang here, more of a general one, but generally speaking, when you're making judgements about infidelity as someone not part of that relationship you're working off very limited information, doubly so for a public figure that you don't know personally.

Obviously it's somewhat complicated when subordinates and Chinese spies are involved, and I'm not condoning infidelity, but IMO infidelity is a reason for a spouse to be justifiably outraged, not the public at large.
