Since the word has this power due to it's history I try to respect the people who lived that history and don't like that word in any circumstance. I feel if your not black and wouldn't say nigga in front of older black folks out of respect why feel it's cool to disrespect me or younger blacks? Also, even though Mexicans don't say wetback, etc. like blacks say nigga, i've seen on here and in real life Chicanos and Mexicans either clowning or insulting each other with that term, then I've seen some white or dumb ass black fools think they can say it because they heard they mexican potna say it and it's all bad.
You used to get this shit all the time on the East COCO forum some norteno calling some fool a scrap wetback paisa or whatever some white norteno jump in and say it, then all the mexicans North and south on his dumbass. It's group language, and I think the same applies for the word nigga.
