I don't have children, don't plan to have children, and don't
particularly want children. If I were to adopt children, my main
criterion would be that they be old enough to operate the vacuum
and do some light dusting. So same-sex parenting is not an issue
with which I have a deep personal connection.
Except that the religious right is making it personal. Their
most popular argument against same-sex marriage goes something like
this: to endorse same-sex marriage is to endorse same-sex
parenting. Same-sex parenting is bad for children, since it
deprives them of either a mother or a father. Therefore, we ought
not to endorse same-sex marriage.
It is not surprising that arguments against same-sex marriage
quickly morph into arguments against same-sex parenting. For one
thing, the tactic is rhetorically effective: indeed, it has more
than a faint whiff of "scare tactic." Less cynically, there is a
significant connection between marriage and parenting, which is not
to say that children are the only reason for marriage or that other
reasons (such as mutual support) are insufficient by themselves. In
any case, the argument cannot be ignored.
Does an endorsement of same-sex marriage necessarily entail an
endorsement of same-sex parenting? It seems not. One does not have
to be married to have children, and one does not have to want
children to be married. Indeed, we allow people to get married even
when everyone agrees that it would be undesirable for them to have
children (e.g. convicted felons serving life sentences). So the
connection is not automatic.
Still, public policy is often based on averages, not necessary
connections. On average, heterosexual couples produce their own
biological children; homosexual couples never do. If they want
children, they must adopt, use reproductive technology, or
otherwise go outside the relationship. This fact is at the crux of
the argument.
As an aside, it's worth noting that gays who want children do
these things already, even without the benefits of marriage. (So do
many straights.) Unless opponents can show that same-sex marriage
would increase the prevalence of non-biological parenting, their
argument falls short.
But do gay couples "deliberately deprive children of either a
mother or a father"? Consider first the case of adoption. It seems
to me not merely odd, but foolish and insulting, to describe
adoptive gay parents as "depriving" their children of anything,
rather than as providing them with something. Of course, specific
adoptive parents, like specific biological parents, may deprive
their children of all sorts of things (affection, education,
material needs, and so on). But when anyone--gay or straight--takes
a child who does not have a home and provides it with a stable,
loving one, we should not invoke the language of "depriving." To do
so is akin to describing soup-kitchen workers who provide stew to
the homeless as depriving them of sandwiches.
Oddly enough, many same-sex marriage opponents recognize this.
Glenn Stanton of Focus on the Family, whom I publicly debate on a
regular basis, describes the sacrifice of gays who provide a loving
home to orphaned children as "noble" and "honorable;" he has said
the same of single parents who adopt. After all, however bad you
think being raised by two mommies or two daddies is for children,
being raised by the state is surely worse.
So perhaps the deprivation argument applies primarily to those
who use reproductive technology. One might contend (for example)
that mothers who go to a sperm bank, with no intention of including
the biological father in the child's life, deprive that child of a
relationship with its father. That, indeed, is Stanton's position,
and he holds it whether the sperm-bank patron is homosexual or
heterosexual.
Whatever you think of the merits of this argument, it has
absolutely nothing to do with same-sex marriage. The vast majority
of those who use reproductive technology are heterosexual. Why,
then, bother gays about this? As William Saletan wrote in
Slate, "You want to stop non-biological parenthood? Go
chain yourself to a sperm bank."
Presumably, the same considerations would apply to those who
create a child by having sex with a third party outside the
relationship. Objecting to their actions hardly provides a blanket
argument against same-sex parenting, much less same-sex
marriage.
To argue against same-sex marriage on the grounds that it
deprives children of a parent is like arguing against same-sex
marriage on the grounds that it leads to divorce: yes, it sometimes
does, but so does heterosexual marriage, and far more often in
terms of raw numbers.
So even if we grant the controversial assumption that
deliberately raising children apart from their biological parents
"deprives" them of something, the deprivation argument proves both
too little and too much. It doesn't apply to most same-sex couples
(few of us have children, and fewer still by insemination), and it
applies to many heterosexual ones. In short, it's a red
herring.
