British health service says marrying your first cousin has many benefits and "economic advantages"

Did you think the headline was a joke? The UK's National Health Service is the country's government-run (socialistic) healthcare system. Last week, NHS England's "Genomics Education Programme" seriously published guidance that said incest is okay, even if such inbreeding comes with double the risk of genetic defects (this is basic science, folks!). Even dumber (somehow) is the fact that the NHS uses King Henry VIII as an example of cousin marriage. Are the people in charge of the UK's healthcare system actually this dumb? (Intelligence is affected by inbreeding too!) Divorcing your wife and marrying her cousin is not consanguineous...
