I think it's always great to ask questions respectfully, as the OP has done.
Anything is possible, and maybe siblings who want to marry exist.
We've had gay marriage in SA since 2006, and there hasn't been a single case of gay or straight siblings demanding to marry.
Currently gay marriage is the same as heterosexual marriage: the two partners must be 18 or older, they may not be blood relatives, and they may not
be directly related to a former spouse.
We also have customary marriage, which allows for polygamy, for example our Zulu President has four wives.
So far there have been no attempts or demands for gay customary marriages with polygamy.
No religious group has been forced to marry gay people or to accept gay married couples into leading church positions. The Dutch reformed church
accepts gay congregants, for example, but gay ministers must be celibate. Both same-sex and religious rights are secured by the Constitution made
Gay and straight couples can qualify for adoption or artificial insemination.
The state doesn't really pay for the latter, although I see nothing wrong with a little help from science for any couple that wants to have
Where one partner is HIV-positive (and we have 6 million mainly heterosexual HIV-positive people), couples can also conceive a healthy child with
"sperm washing" (although it costs about R15 000).
There are many cultural differences about "adoption", and traditionally in African society an orphaned child would be absorbed into the extended
For a couple to adopt a completely unrelated child was not customary.
The HIV/AIDS crisis was however so severe at a stage that adults were dead or dying, and sometimes households were headed by children or by very old
Economics have changed a lot.
Whites used black maids to mother their young children while the parents had daytime careers, and the state cared for orphans and old people.
Blacks did get a pension, but they relied heavily on their children and extended families in old-age, which was an incentive to have large
Now the available distribution of funds is more equal, which means that whites no longer employ as many maids, and unemployed young and old people may
share a home.
I know at least two gay people that care for the children of their siblings during the day.
It's in more extended communal living like this that gay people can really be appreciated.
I know cultures differ on what defines "incest", especially regarding cousins.
However I can't think of a single culture that would allow a biological brother and sister to marry.
Maybe in ancient Egypt, or in the days of the Hapsburg dynasty.
I've heard of siblings that married by mistake, and subsequently found out they were brother and sister.
Here the authorities have been known to turn a blind eye, especially if the kids turned out normal or there is infertility or sterilization.
I think it's so alarmist to say that gay marriage will lead to this or that.
That's like saying if the conservatives get their way adultery or divorce will become illegal, and a raped virgin will have to marry her rapist
(according to Old Testament Law). Traditional marriage has also changed a lot, from a female age of consent of 12 in the late 19th century to Jerry
Lee Lewis marrying his cousin of 13 in the late 1950s. That was "traditional heterosexuality" in some places that would now be unacceptable.
A much greater debate will develop around the older spectrum of women's fertility.
Now that 40 is the new Western 20, should science help heterosexual couples have kids into their 60s?
There's a chance of something going wrong.
But isn't there always?
I think this will become a bigger moral and social issue than alarmist arguments of incest, bestiality or child-marriage.
I'd like to engage those issues here, but there hasn't been a single case since 2006, at least not for gay marriage.
