Here's why:
* Nationality is complex: Nationality can be based on birth, citizenship, or self-identification. Someone may have Mexican parents but be born and raised elsewhere, becoming a citizen of that country.
* Identity is personal: An individual's identity is unique and influenced by many factors beyond their parents' heritage.
* Labeling can be harmful: Using labels like "not Mexican" can be disrespectful and reinforce harmful stereotypes.
Instead of focusing on labels, it's better to:
* Ask respectful questions: If you're curious about someone's background, ask them directly and respectfully.
* Focus on individual characteristics: Get to know the person for who they are, regardless of their background.
* Celebrate diversity: Embrace the richness that comes from different cultures and experiences.
Remember, it's always best to treat everyone with respect and avoid making assumptions about their identity.
