The nuclear family we see today is basically the smallest most regular social structure. Others exist like the company or the church, but at the end of the day most people ether live alone or within one of these family units.
That said, I'd argue this is actually not the most ideal structure, as it often results in those who live in ways that differ (gays, unmarried, alone, single mothers, etc) being unfairly shunned simply for not conforming.
With this, I'm just curious, Are there any examples in history of a family structure that could serve as a possible replacement for the nuclear family?
ps: Apologies if my questions suck, I'm new to this part of stackexchange.
