Look my guy. We're brainwashed by Internet.
I don't believe saying N word in the context of non-offensive joke makes you Racist. Because if Racism is when you hate other people for being different than you. Tell me how I would be racist for saying it, even thought I have met black people in my life and I actually had friendly interactions with them, just because of a word that was not even directed to them?
Morgan Freeman, a black person himself said that the racism will stop when we stop mentioning it.
Someone asked him what race he is, he responded with "I'm Human race".
If we keep saying that "racial sure there, racial sure here, he said that..." instead of not caring for it. Maybe the Society itself would be already united for ONCE.
