Marriage and legal rights cannot just be for a select few in society. There are legit reasons why this legislation requires modernising, just as the UK has seen a modernisation of marriage laws for same sex couples in recent years. Polyamorous relationships are just as real and legit as monogamous, but without legal rights to marriage.
