The recent statement by Madrid's mayor suggesting that Mexicans don't know their own history has sparked significant reaction, particularly concerning the Aztec civilization and Mexico's indigenous heritage. Living in Mexico and exploring this rich history personally, I have found that Mexicans generally have a deep understanding and pride in their cultural roots. Many locals are aware of the complexities beneath places like Guatemala Street in Mexico City, where Aztec ruins and relics lie underground, reflecting a past filled with both grandeur and tragedy. What I noticed from conversations and tours is that the Aztecs, while often glorified for their architecture and social structures, also practiced human sacrifices, a fact well-known among Mexicans and acknowledged openly in educational and cultural discussions. This nuanced perspective shows that Mexican history is not about myth-making but an honest recounting of all facets, including difficult truths. Moreover, the shift from traditional Aztec foods to colonial influences, like pozolle made once with human meat but later replaced, is part of a broader narrative about cultural transformation due to colonization. This transition is something that many Mexicans understand as a significant part of their identity evolution. Conversations with residents and scholars reveal how indigenous beliefs about purity and cleanliness contrast sharply with the colonial perspective that labeled native people as 'dirty.' Such historical insights highlight the layers of misunderstanding and stereotypes that have developed over centuries. In sharing this, I emphasize that Mexicans are not ignorant of their past; rather, they engage with it critically and proudly, navigating the blend of indigenous and colonial histories to form a unique national identity. This rich understanding is something to appreciate and respect beyond superficial judgments.
