Human beings socially construct many things, I don’t see how that statement can be followed by “therefore make way for gay marriage”.
Rather it is followed by the dismissal of an argument that relies on
marriage being a thing “in nature” rather than a social construct.
Would you like to take up P_S’ assertion that marriage is a thing “in nature” (and what do you mean by that)?
If all marriage is pure social construct, what is it exactly that is being constructed? I would like you to expound on that, what actually does marriage mean?
The social construct is the thing being constructed, if that is what you mean?
I’ve given three different things that are referred to as ‘marriage’, but in each case I would say that the thing being
recognised by [society/religion/law] is the human equivalent of a pair-bond in nature. (Possibly involving more than two people, if you insist, although I have always viewed polygamy as multiple two-people marriages rather than one marriage of more than two people)
When two (or more

) people form a pair bond, share a house, wealth, possessions, possibly raise kids together and so on, all sorts of issues arise. For example, when one eventually dies, it would not be nice for death duties to force the other to sell their house and move home at a time when they already have to deal with grief, probate, funeral arrangements and so on. To this end, marriage law acknowledges the pair as effectively a single economic unit, which does not have to pay death duties until
both are dead. How is this less applicable to a same sex couple than a heterosexual couple?
You also said “in the past have been referred to a s marriages” what do you mean?
In the literal sense. See my posts above. Other cultures have in the past referred to two men or two women as married.
Good question, The definition is limited because it makes logical and historical sense to define it as the conjugal union.
No, you don’t answer my question, you just repeat the assertion that that is what marriage means, according to you. Why do you want to insist that ‘marriage’ has never been used to refer to same sex couples, when it has? Given that many many people use the word today to refer to same sex couples, and that their meaning is clear and unambiguous, why do some Catholics try to just insist that SS’M’ (as they condescendingly call it) is intrinsically meaningless rather than explaining why they think it is a bad idea?
The government doesn’t recognize your marriage because “aww they love each other and are deeply committed personally to one another”.
Neither does it recognise your marriage because you can put a penis into a vagina.
See, anyone can ridicule the other side.
If we perpetuate the notion that parents are not mother and father, but merely two people raising a child, the government is by default actively involved in assigning who’s the “real mother” and being actively involved in keeping the child away from his/her biological parents.
Extraordinary assertion. Why is the Government forced to do any of this? How is this not the case with heterosexual couples raising children from previous marriages, adoption or surrogacy?
With “gay marriage” comes the idea that biology has no ground in parenthood either, a parent becomes whomever the government decides is a parent or whomever he or she chooses to be, Motherhood and Fatherhood are merely nominal, ungrounded in biology (very messed up).
Nonsense. At most you disassociate ‘marriage’ from ‘biological parenthood’ - but since the two are often not the same even in heterosexual marriage, and since studies show that same sex couples do a very good job of raising kids, what here would justify State discrimination against same sex couples?
I really don’t see why gay couples need the government to tell people that they love each other. It has no logical ground at all.
Why do heterosexual couples need the government to tell people that they love each other, then? Is it possible that this is nothing to do with the reasons for marriage and that you are just being condescending to homosexuals?
You assume “gay marriage” is in fact marriage.
You assume that it is not marriage, as opposed to simply saying that it is a form of marriage of which you disapprove.
You have yet to explain why (at least some) Catholics want to simply dogmatically define it out of existence rather than justifying your opposition.
