Welcome to people who still can't come to grasp with the modern reality that there are a large number of multi-ethnic (and even multicultural) families where not all relatives share the exact same ethnic relationship backgrounds and even direct genetic or bodily fluid-exchanging relationships are not necessarily connecting all the relatives.
I can't wait to see how they are going to react when people start showing birth certificates listing three parents. Will they then start asking everyone without a birth certificate to prove they don't have three parents and that the two parents of the child aren't trafficking/kidnapping their own child?
The national paranoia knows few/no bounds, and its oxygen is ignorance.
