* Constantly Evolving: Language is dynamic. New slurs emerge, and some fall out of use. What was considered offensive in the past may be less so today, and vice versa.
* Subjectivity: What constitutes a racial slur can be subjective and depend on context, intent, and cultural understanding.
* Regional Variations: Some terms considered slurs in one region might not be in another.
* Difficult to Categorize: Many words can be used both innocently and offensively depending on the situation.
Instead of focusing on a specific number, it's more important to recognize the harmful nature of racial slurs and strive to use inclusive and respectful language.
