• Sommario/riassunto: Wat beweegt jongeren om zich aan te sluiten bij extreemrechtse organisaties en zich in de marge van de samenleving te bewegen? En waarom keren ze extreemrechts later weer de rug toe? Die vragen stelden onderzoekers van de Anne Frank Stichting aan twaalf voormalige rechtsextremisten. De onderzoekers interviewden mannen en vrouwen die veelal tot de harde kern van verschillende rechtsextremistische organisaties hebben behoord. De onderzoekers concluderen dat voormalige rechtsextremisten een nuttige rol kunnen vervullen bij het deradicaliseren van leden van extreemrechtse bewegingen. Wanneer zij n
