@shortstories I think you are a bit lost in the weeds by making this out to be a hypergamy issue. I doubt there was any sex going on between the two of them, but rather the "marriage" was just a way for them to fraud the immigration system.
I could be completely wrong about that, but I think that it is bad enough that they were committing fraud without allowing some "fact checkers" to "debunk" this by proclaiming it is totally false because no sex (apparently) took place.
