Despite the recommendations of the European Commission Against Racism and Intolerance (ECRI, 2024) higlights the urgency of addressing racism, discrimination, and hate speech against ethnic and religious minorities, empirical research on these issues remains limited in Italy, a country facing rapid cultural changes. This project addresses this gap through two complementary studies examining the psychological impact and social acceptability of ethnic and religious microaggressions among minority and majority groups in Italy and Belgium. Study 1 explored how experiences of microaggressions influence stress, life satisfaction, and psychological well-being among ethno-religious minorities (N = 268) in Italy. Microaggressions were assessed using an adapted version of the Racial Microaggressions Scale (Torres et al., 2018) and the R28-Racial and Ethnic Microaggressions Scale (Forrest-Bank et al., 2015). Results showed that discrimination in interpersonal interactions significantly increased psychological distress, with this effect moderated by perceived social support. However, microaggressions did not directly influence life satisfaction, which was instead explained by identification with one's religious community. Study 2, investigates the acceptability of microaggressions as defined by Mekawi and Todd (2018) - the extent to which microaggressive attitudes or behaviors are perceived as appropriate or unproblematic. It further examines the mediating role of colorblind ideology, hypothesizing that higher colorblindness among majority members predicts greater acceptability of microaggressions, whilst lower colorblindness among minorities predicts lower acceptability. Together, these studies enhance understanding of how microaggressions affect minority well-being and how they are normalized or challenged in European contexts, providing empirical foundations for interventions fostering inclusion and equality.
