they can, but the argument is near 100% about what 2 adults want and their rights ect... no one mentions the point of the marriage beyond the title and bit of paper you sign. im just raising a point ive heard a few times now. that people see all this marriage arguments as missing the point of what it was in the first place, the contract to stay together for the good of the family, at least until they are old enough to not be effected. the idea of a marriage been not that serious and everyone can have one then just split up is seen as removing the drive and social expectation to stay as a couple to raise a kid. obviously alot of factors in single parent rates, but devils advocate, that is a legit worry people have
