Once upon a time, the societal formula for weddings was pretty limited: boy + girl + religious ceremony = wedding. Period. Anyone who deviated was...well...a deviant, subject to social and legal marginalization. Similarly, for many years our culture supported a narrow definition of family, namely family = a husband + a wife + their biological child(ren). Period. Unmarried parents, same-sex parents, interracial families, immigrant families, blended families, families of color, families without children, and even adoptive families struggled to find their place in society, facing a range of difficulties and indignities at every turn.
