By the early 21st century, many white Americans celebrated the impact of African-American culture, especially in sports and music, and marriages between white Americans and African-Americans were becoming much more common. Israel Zangwill saw this coming in the early 20th century: "However scrupulously and justifiably America avoids intermarriage with the negro, the comic spirit cannot fail to note spiritual miscegenation which, while clothing, commercializing, and Christianizing the ex-African, has given 'rag-time' and the sex-dances that go with it, first to white America and then to the whole white world."
