This article proposes some reflections on research or interventions relating to issues that concern and affect us. The English term would be “insider”. As researchers and social workers with an immigrant background, our personal experiences are also part of the issues we deal with concerning vulnerable populations: the descendants of racialized migrants, the children of racialized mixed couples, LGBTQ migrants and racialized persons. We will therefore address, through our respective objects of engagement, how working with racialized populations re-actualizes experienced forms of exclusion while giving rise to new questionings feeding our research.
