The Dutch have always been welcoming and laid back since coming out of WWII. But today's realities are very different. They are dealing with millions of migrants/refugees who have never experienced living in a "liberal" society. Newcomers only know and only abide by to the law of God (Koran).  Liberals in Netherlands follow common law/constitution and civilian judicial system. Also language barrier and literacy issues compound the problems. Communication breakdown between newcomers and hosts naturally makes them fear one another.
