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”.
That’s already a lot but apparently in the UK which the article is about it is now over 50%
There are far fewer practising Christians in the UK. Also there’s no tax incentive favouring marriage, everyone files separately.
