Nah... it's a valid question. Not all blacks are niggers, just like not all whites are crackers, and not all mutants are muties.
If you're person and start throwing out racial slurs, especially about people with real accomplishments (say what you want about him, Chuck is a military vet, has a PhD, and is considered a leading authority on mutation and genetics - even Reed Richards will consult with him).
The punk with his pants down around his fucking knees standing in front of you at the gas station saying "yo, give me a pack of Kools and some grape soda, muthafucka," then pays with some dirty bills that were obviously stolen from his grandma's purse and drops his crack pipe on the counter by accident, probably a nigger.
The surgeon who spots the tumor that the other doctors missed on your MRI who then performs life-saving surgery on you using a technique he pioneered - fine upstanding African-American member of the community who is a credit to their profession.
