This is a term for people who are of a multiracial ancestral background. Instead of "multiracials" which does not specify that it is referring to multiracial PEOPLE, multiracialers would make it clear that it is referring to those who continue on "multirace-related" throughout their lives. The term "multiracialers" is more brief than the term "multiracial people" which is longer, and the term "multiracialers" also avoids the confusion that "multiracers" may produce, whereby one may confuse it for referring to those who are competing in multiple races at once.
Many multiracialers find themselves facing great confusion over their identity in their teens and early twenties.
