Home-schooling is illegal in Germany. So, "In 2008, Uwe and Hannelore Romeike left Germany with their five children and came to the United States asking for refugee status as an oppressed minority."
So they left Germany to seek asylum in Left-Fascist Amerika. There is a touch of irony here. Well, we are not as far gone as the "land of poets and thinkers." (Heinrich Heine) Not yet, leastways.
The reason for the disallowance of home schooling is that the powers that be don't want the formation of "parallel societies" (Parallelgesellschaften). That's a real knee-slapper given the green light to Muslim immigration and the Islamization of Germany. No "parallel societies" unless they are politically correct parallel societies.
The Pee Cee, you see, are 'inclusive.' Even unto their own extermination. The Germans seem especially PC-whipped.
It is perhaps not irrelevant that the Romeikes are Christians. Nor that ". . . one of the oldest universities in Germany inaugurated the country's first taxpayer-funded department of Islamic theology. The Center for Islamic Theology at the University of Tübingen is the first of four planned Islamic university centers in Germany." (Ibid.)
