Race is a product of racism, so groups are racialized rather than racial.

Evidence

It is more accurate as a consequence to speak of a racially fashioned or created (or more commonly, if awkwardly, of a “racialized”) group than of a racial group since race is a product of racism and not vice versa. It is also and relatedly important to note that the now popular if overused notion of “racialization” and its cognates (“racialize,” “racialized”) are ambiguous. They fail in their often facile usage to distinguish descriptive context from normative critique, analysis from dismissal, processes of race-making from critical rejection of racist implications. — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 107
