Russian dating and marriage traditions
Many cousin couples can't pass on genetic diseases, since they're infertile. If not, maybe the 24 states that ban cousin marriage should follow the lead of the five states that allow it if either party is sterile. If your purpose is to prevent people with dangerous genes from marrying each other, why use a crude standard such as kinship?
And if procreation between first cousins is too dangerous, why stop there? Why not test everybody for bad genes, ban marriage between carriers, and let cousins without bad genes marry each other?
You can't just say the practice in question is icky.
You have to state a principle and think through its implications. You can't appeal to Victorian morality; Queen Victoria married her first cousin.
Science has deflated the scientific objections to cousin marriages. North Carolina and West Virginia explicitly prohibit me from marrying you, but 20 other states don't. Because if it is, bear in mind that you and I have as many genes in common as an uncle and niece do.
If you and I can marry, why can't an uncle and an adult niece? Would you rather restrict marriage to ordinary first cousins? First cousins have as many genes in common as a man and his half-brother's child do. If first cousins can marry, why can't Roger and Chelsea? If you still won't cry uncle, let's look at hard-core incest.
To get the disease, you have to get the bad gene from both parents.
From this, the media have concluded that marrying your first cousin is "OK." Is it?
As Frame Game has argued before, topics such as sex with animals, dog-eating, and sex with cousins are never as simple as they're made out to be.
One doctor calculated from the study's findings that "almost 10,000 children will be stillborn or born with birth defects this year in the United States from first-cousin marriages.
Not marrying a cousin is a more potent remedy than many of the medications we prescribe for heart attacks." Perhaps states should at least require cousins to get genetic counseling before marrying, as Maine has done.
