"Using breakfast tacos to try to demonstrate the uniqueness of Latinos in San Antonio demonstrates a lack of cultural knowledge and sensitivity to the diversity of Latinos in the region," the organization wrote. "NAHJ encourages Dr. Biden and her speech writing team to (take) the time in the future to better understand the complexities of our people and communities.
"We are not tacos. Our heritage as Latinos is shaped by various diasporas, cultures & food traditions. Do not reduce us to stereotypes."
