This chapter explains very large segments of the people of free society's sense that they are threatened by massive immigration and by the growing minorities within their borders that hail from different cultures, follow different practices, and have separate institutions and loyalties. Furthermore, telling people that they 'need' immigrants because of economic reasons or demographic shortfalls makes a valid and useful argument, but does not address their profoundest misgivings. Almost all of these nations now face massive immigration and growing numbers of minorities that believe in different religions, especially Islam. The assimilationist model assumes that immigrants and minority members of society will be taught in public schools, and that they will be taught basically the same material as other members of the society and more or less the same material as were previously provided.
