A Danish professor of criminal justice ethics has stated that he thinks consensual sex between adult siblings should be legal. According to Thomas Søbirk Petersen, a professor at Roskilde University, the rise in the number of births resulting from donor sperm, which has the potential to create biological siblings who are born into different families, has created a need to rethink the "old taboos" against incest.
“In a society where more and more children are being conceived using donor sperm, the risk of falling in love with a stranger who turns out to be a biological sister or brother has increased," Petersen told MetroXpress. Petersen said he believes that siblings who want to have children together can reduce the risk of having a handicapped child by themselves using donor sperm or eggs – and then there is always abortion as a backup. "Should they be jailed for up to two years, as is now required under law?” Petersen asked. Petersen said that he wants to see a debate on legalizing incest in Denmark along the lines of that which took place in Germany last month, saying that he thinks "it's a cop-out that a democratic society is not willing to discuss this."
In September, a German advisory council on ethics told the government it should decriminalize incest between consenting adults. The National Ethics Council voted, by a two-to-one margin, to call for the decriminalization of incest. “Criminal law is not the appropriate means to preserve a social taboo,” the council explained in a statement. “The fundamental right of adult siblings to sexual self-determination is to be weighed more heavily than the abstract idea of protection of the family.”
However, Jeff Johnston, issues analyst for Focus on the Family, denounced the concept that protection of the family is an "abstract idea." “If the German government follows this council’s recommendation and legalizes adult incest, children will be irreparably damaged. It's unconscionable. Children are protected by laws against incest from being sexually abused by family members. These aren’t ‘abstract ideas,’ but are common sense standards that give real people—our children—the best chance to grow up in safety and security,” Johnston said.
The miasma of complications resulting from numerous children unknowingly being related to each other because they were fathered by the same anonymous sperm donor was highlighted in a 2011 New York Times article titled, “One Sperm Donor, 150 Offspring.” The article narrated a woman’s search for her own child’s siblings, all of whom were the offspring of the sperm donor who fathered her child. When she completed her research, she was shocked to find that the man had fathered 149 other children, all of them half-brothers or half-sisters of her child.
The Times article noted that an immediate concern was the possibility of one sperm donor passing on a rare disease to many children. [...] “Sperm banks and fertility centers are running a mostly unregulated 2-billion dollar industry annually and are churning out mass produced children the way the auto industry produces cars,” wrote Dr. Hunnell. “In fact, there is more concern about the health and safety consequences of a minivan than there is about the health and safety consequences of children conceived with donor sperm.”
[...] According to the MetroXpress report, the Danish ethics committee has not taken a position on legalizing sibling incest, but committee vice-president Professor Gorm Greisen said that making the act legal would "open the way for completely new and complex issues."
