Double standard(Who can use the N word?)

WHAT UP DOE DETROIT, this is MegaHertz with another question to ask my kinfolk. Im not gonna lie to you and say hey I dont use that foul language! We are all adults here, you pay bills and taxes you have the freedom of speech? or do you? I work for the Detroit Metro Airport,were its mostly 90% black men that work in my field. It can get real heated in that small sticky lunch room were in the summer its hot and sticky, and in the winter its colder inside than out.
Men 18-24 make up the about more than half of the employees, and its alot of intresting topics we talk about. But I seen somthing the other day that had me clueless. At lunchtime some guys were sitting eating lunch and listening to the sports radio station, and the host said should Michael Vick be allowed in the hall of fame. Out of nowhere is young white man from Inkster said in a so called "kool" voice man that "Ni99a should burn in hell. I was like WTF but the other guys didnt even look at him. Is it ok for "Kool,or from the Hood white men to say the N word. Let me know!
