Yes, I can. The normalcy of a thing doesn't make it right. But this isn't really about whether absolute cultural relativism is appropriate or not. It's about a man who broke his word. Huang wed an American woman in America, not a French woman in France. Nothing about this situation indicates Huang's wife was remotely aware of nor alright with his philandery.
> Huang wed an American woman in America
Please don't make the mistake of assuming that American culture is homogeneous: It's not.
Wait till you hear about what wives get up to at “board game night” in San Jose.
After looking up Huang:
He is an immigrant, he holds dual citizenship in Taiwan, and regularly travels there.
I didn't go so far as to find out if he married in the US or elsewhere, or if his wedding was Christian.
What I do now is that in some cultures in that part of the world, it is acceptable for a man to visit a prostitute during a business trip. It's not something I condone.
I should also point out that in the US, there's no standard wedding vows! I don't think you know what vows Huang made with his wife; nor do I think you know what their expectations were in their relationship.
