I am trying to translate Osamu Dazai's essay 如是我聞(Thus I heard from the Buddha) into English.

Here is a part of my translation:
There is a group of old "moguls". I have never met any one of them. I have been amazed by their confidence. Where does that come from? What is their "god"? Recently I have found it out at last. It is their family, or rather, the ego of their family. That is their true religion. I think I was deceived by them. To use a vulgar phrase, it's just that they love their f***ing family.
The original text:
My question: Is the following sentence grammatically or semantically, or in whatever sense native English speakers have, correct?
To use a vulgar phrase, it's just that they love their f***ing family.
I ask this because "they" is plural, but "their f***ing family" is singular. It seems to me that "they just love their f***king families" is a bit unnatural.
Each member of the group of the moguls has their own family.
