It's about tearing down another family value that is held dear in nuclear families, especially multi-generational families where everyone gets together at the end of the day and talks about the day's travails.
The problem is that today's minority families don't exist anymore. Single mothers, multiple father siblings, no work ethic, all contribute to the decline of certain blocks of people.
So the only thing left is to mock and deride those true families that do stay together, and dine together.
