This is a great example of appropriate use of an offensive word, (the N word) I do not believe it is intended to be hateful or derogatory in any way, it's use is clear and concise. And I would be surprised if it offended or was removed.
Sometimes you manage to be offensive and still be PC, again I don't think being PC is the issue, I do not have issue with how you say things. I do however often take issue with what you are saying.
In saying all that I would not wish for you leave,
but would ask you to consider how strongly you stand behind your beliefs and ask would you ask any of us to be less committed to ours.
my 2 cents, for what their worth.
