Phoenix Dark, as usual, is a fucking distinguished mentally-challenged fellow.
Example.
1. Walking down the street, I call the first person I see a "n1gger." This person, being white, takes no offense to the term and thinks I am crazy.
2. Walking down the street, I call the first person I see a "taco." No matter what their race is, as long as the understand the language, they think I am insulting their sexuality.
There you have it, 100% conclusive proof that "taco" is the more offensive slur. Calling someone a "n1gger" is like saying "shucks" instead of "cool" in the 80s.
