After we send him to Germany we should ask him to make a side trip to Egypt where the full face covering is now being banned by the el Sisi government.  It is being banned there for the same reasons that Germany and several other countries are now banning it. - the full face covering promotes the separation and ghetto existence of Muslims, in turn this ghetto life promotes radicalization and terrorism and, to the degree that it is forced upon women, the full face covering is another means to marginalize Muslim women and ensure their subjugation to men.  Interestingly, Egypt is about 90% Muslim so even The Boy Blunder may have a hard time labeling the Egyptian president (who is himself a Muslim) as being anti-Muslim.
