During the late 19th and early 20th centuries, what role did stereotypes play in the perception of immigrants?

The correct choice highlights how stereotypes during the late 19th and early 20th centuries significantly influenced the public perception of immigrants. Stereotypes portrayed immigrants as violent criminals, incompetents, and unworthy of the rights and respect afforded to native-born citizens. This negative characterization was often fueled by xenophobia and cultural misunderstandings, leading to public fears and hostility toward immigrant populations.

These perceptions contributed to social and legal discrimination against immigrants, including restrictive immigration laws and the establishment of quotas that favored certain nationalities over others. Stereotypes were powerful tools that shaped societal views, making it difficult for immigrants to integrate and gain acceptance in a rapidly changing America.

In contrast, the other choices do not accurately reflect the historical context. Stereotypes did not aid in the social acceptance of immigrants; instead, they often created barriers. They were certainly relevant to public perception, shaping opinions and policies decisively during this period. Furthermore, many stereotypes were not grounded in extensive research but rather in fear, prejudice, and misinformation.
