Poland, the Czech Republic and Hungary are countries that did not participate in colonial conquests. Therefore, they did not bring to their territories larger groups of people of different racial, national and religious identity. The ways of living together in one country with citizens of different races, nationalities and religious beliefs are not known here from personal experiences of the last 70 years. Opinions on the possibility of co-existence and integration of so-called ‘strangers’ are based only on the opinions presented by publicists and politicians. As is known, the political and military events that occurred in the last few years in the countries of North Africa and the Middle East have led to the exodus of refugees, the emergence of the so-called Islamic State and acts of terror . These events, of course, are widely commented on by Eastern European publicists and politicians. They also comment on the average beliefs and attitudes of Muslims and analyze in particular the possibility of integrating refugees in Western societies, especially the phenomenon of so-called ghettos.
