The meaning of assimilationism is the act or policy of encouraging immigrants or minority cultural groups to be similar to larger cultural groups, (especially by intermarriage). In other words, it’s mixing of different cultural groups. In USA assimilationism was popular from nineteenth century until the end of twenties century. In the beginning of 18th century when assimilationism was observed, native Americans tried to give their vernacular language and clothes, attitudes or even teach the ethics to immigrants or minority groups. Assimilation declined in 1980-1990 due to growth in immigrant population. When it comes to play “Raisin in the sun” the character “Beneatha” seems to be the most important in aspect of assimilation. George and Asagai are two men in her life, they are expressing opposite sides in the case of assimilation. The character “Asagai” represents native African identity who are denying assimilation. The character of George tends to be similar to white man. George’s character is typical identity who has conformed American standards. In the play, Asagai said that “Assimilationism is so popular in your country” while Benetha claimed “I’m not an assimilationist (63)”. In my opinion, they argued because the character Asagai thinks that many Africans forgot their ancestral African roots while the character Benetha claims that she’s universal person and doesn’t forget her heritage. In next case of assimilation debate might be the part of play where the character Benetha changed hairstyle. While Asagai encourages her to wear naturally and similarly to her native identity, George ashamed by touching her hair and said “Girl, you done lost your natural mind? Look at your head! (80)” and also ” Let’s face it, baby, your heritage is nothing but a bunch of raggedy-asssd spirituals and some grass huts! (81)” . George has already became MAN and lives in MAN’s life so it looks weird for him. These characters “Beneatha, Asagai, George” represents opposite perspectives of assimilation in America.
