Midwives have been told about the benefits of “close relative marriage” in training documents that minimise the risks to couples’ children.
The documents claim “85 to 90 per cent of cousin couples do not have affected children” and warn staff that “close relative marriage is often stigmatised in England”, adding claims that “the associated genetic risks have been exaggerated”.
Do you think it’s (morally) right for you to have kids that you know would have a 50% chance to have bone tumors?
Sex bans are generally not workable. A marriage ban for you would be restrictive. This is very different for cousins, because there’s plenty of non-cousin alternatives for everyone.
