There's also another, darker side to this. Great Britain has dealt with it and still is. Muslims traditionally marry within their family--cousin to cousin. The resulting birth defects are extremely serious and drain medical resources. There is enormous social pressure for them to marry this way, parents heavily involved in spouse choice. The younger ones, at least some of them, are trying to end this.
They also have "double cousin" marriages where the parents of both spouses were cousins (same sets two sons marry the two cousin daughter eg) and the children marry making them essentially biological siblings
They do. And most of them, especially the older ones, just accept that a great many of their children will die very young or suffer degenerative diseases. There is hope with the younger ones, who are better informed and just refuse to accept that much horror and sorrow. One cousin couple only found out about these problems after they married and had themselves sterilized.
