It is common to say that word in my area of the world as well. I personally do not have any issues with it. I have never said it but I hear it all the time. My son and his best friend who is black say it to each other all the time.
Unfortunately some peeps take offense to it. Is probably why you were banned.
We live in a world of pussies now. Everyone gets offended easily and that is why there are so many fucking safe places LOL
It is hard for some of us that have different opinions than those pussies that sometimes some peeps give in rather than fight against them.
As a handful of XI members who know me know I will say what I want, to whom I want, when ever I want. I have never been afraid to voice my opinion. I will show respect while I am voicing it but I will never give in when I truly believe in doing what's right.
