A member of the French assimilationist tradition, Zemmour strongly opposes immigration and the current model of integrating immigrants which he considers to be too lenient in comparison to its predecessors. In November 2008, he gave an interview to the monthly "Le Choc du mois" where he compared immigration to a "demographic tsunami" He has also come out in favor of the Thierry Mariani amendment, which would require genetic tests in order to qualify for family reunification. On numerous occasions, he has declared that he is for assimilation, even if he himself considers it "neurotic". In particular, he expresses a nostalgia for the era of his youth, the 1960s, when there was a cultural unity.
