A person who believes that people from different groups should adopt the dominant culture's practices and way of life.
From 'assimilation' + -ist (one who practices or believes in). Became a historical term in 19th-20th century discussions of immigration and cultural policy.
Assimilationists believed in a 'melting pot' where everyone becomes the same, but 20th-century researchers discovered that multicultural societies ('salad bowls') actually thrive better, making old assimilationist policies look scientifically backward.
