Final answer:
Black writers have a cultural and social responsibility to use vernacular language to resist marginalization, maintain authenticity, and authentically represent the diversity of Black experiences.
Step-by-step explanation:
The responsibility of Black writers toward the use of vernacular can be seen as part of a broader context of asserting cultural identity and challenging the norms that have historically marginalized African-American speech. Drawing from the Harlem Renaissance, writers like Langston Hughes, Zora Neale Hurston, and Claude McKay embraced vernacular language and African-American themes to communicate social truths, advocate for racial pride, and reflect the lived experiences of Black Americans.
Hurston, in particular, celebrated Black dialogue in her novels, pushing against the conventions of the time that devalued such expressions of Black life. The Conference on College Composition and Communication (CCCC) upholds these traditions, advocating for linguistic rights and against linguistic racism. This suggests that Black writers have a cultural and social responsibility to use vernacular language as a means of resistance, authenticity, and representation of the diversity of Black experiences.
