Cac here. Grew up loving hip-hop, where the word is frequently used. And even though the origin of that word has come from horrible circumstance, blacks have turned a variation of the word into a "positive", by using it as 'dude', 'bro' etc. nowadays. That however does not give me the right to say it as a non-black, and will never say it. I see way more whites use it nowadays (I'm sure with no ill intentions, always hear the excuse "blacks say it with good connotation, so why cant we?"), but it's just not right. There are so may words we can use, I don't see why whites don't just avoid the word all together.
