I've always found that argument strange.
Like preserving the meaning of a word is a reason to justify discrimination...
Also, if you look at the divorce, infidelity, single parents & other marriage statistics - not to mention the stream of atheists getting married - I'm not sure who exactly they think is undermining the "moral fabric of marriage".
What have atheists getting married got to do with 'the moral fabric of marriage'? Surely a philosophical position is immaterial to a social union.
What is the moral fabric of marriage anyway?
Marriage isn't solely a religious institution, it never was and it certainly isn't now....as far as the etymology of Marriage, there is a lot of misconceptions and misunderstanding of its origins being bandied around here and if we look at the actual origin of the modern word from the Vulgar Latin it specifically defines as a bonding in order to procreate as the original meaning related to breeding pairs in agriculture, the association with the Roman
Conubium (the actual legal process) came later, and the term
matrimonium required a woman, and a fertile one at that as the fundamental reason for such a union was procreation and the legal status and heritage of Children.
Today, society is somewhat different, and Marriage reflects that, it is no longer an imperative to have children and modern medicine can, and does solve that issue anyway. We should stop focusing on what tradition states and focus on the social and legal needs of people today. We are striving for an equal society, therefore defining legal status' in a discriminatory way seems to me to be the antithesis to what we, as a society are trying to accomplish.
Does it not?
