Asian Americans, historically oppressed and influenced by White supremacist norms, may internalize anti-Blackness (beliefs of behaviors that minimize, marginalize, or devalue Black individuals) as they navigate White-dominated environments to survive and seek acceptance. However, there is limited research addressing the intergenerational socialization of anti-Blackness within Asian American communities and its impact as a barrier to cross-racial solidarity and involvement in anti-racism efforts. Thus, we tested whether parents' anti-Black messages were associated with fear of Black individuals and lack of empathic reactions to anti-Black racism, and in turn, related to hindrance in the perceived ability to engage in anti-racism advocacy among Asian American emerging adults. With data from 205 participants (Mage = 19.92, SD = 2.64, online convenience sample), we conducted a path analysis of parents' anti-Black messages indirectly associated with perceived ability in advocacy against anti-Black racism through fear of Black individuals and empathic reactions to anti-Black racism. Parents' anti-Black messages were associated with greater fear of Black individuals, which was associated with lower empathic reactions to racism, and in turn, ultimately associated with a lower perceived ability to engage in advocacy against anti-Black racism. This pathway was the best-fitting model compared with an alternative parallel model (fear and empathy as separate mediators) and a model with empathy as the first mediator. Our study suggests that clinicians, educators, and researchers should target parents' anti-Black messages and Asian American emerging adults' emotional responses (fear, empathy) to anti-Black racism in disrupting anti-Blackness at parental/family and individual levels.
