It looks as though the goal was to encourage midwives not to stigmatise people for marrying their first cousins. That seems a good policy when they're delivering healthcare services. But the way the numbers were presented made things appear worse than they are.
I indulge in some risky behaviors (martial arts, skiing, cycling). I don't want lectures about the risks of those, either. If I break a bone, I want it treated, and if the NHS takes a view on the activity that caused it, I'll want to hear it later from my GP, and definitely not at the time I'm seeking treatment.
