I don't think so- it is just history- if anything family bonds were far tighter in Roman times and loyatly to the family was seen as a primary virtue. The core of a Roman family was the "nuclear" unit obviously- but in order to survive families had to include as many "supporters" as they could. Life was short and brutal and the bigger the family- the more protection you enjoyed. This is a far cry from accepting "Gay marriage" which Romans would have thought preposterous.
