Multicultural literature has different definitions depending on who you’re talking to. I think in the extreme people think it’s basically all literature that includes every culture. And that’s fine ideally, but then it means we don’t need that definition of multicultural literature that’s different from literature in general.
I tend to focus my part of focusing on multicultural literature on the literature by and about people of color. I’m willing to expand that definition to include other underrepresented or marginalized groups.
