Oh yeah, I remember the old thread... Those were fun days...
But yeah, this has been discussed to death. But here are my views:
No one should use it.
I don't.
I don't use "a" or "er".
I may say "negro", but I just think that it adds nothing to a conversation.
Free use of the word now has white, and especially latino people saying it.
If I went around calling all caucasians "crackers" or the like, A) I'd feel awkward, and B) It would just not be a good look.
I think that no one should be able to use the word
It should be buried and dead, like the time frame the word came from.
Whenever I hear someone say it, I just cringe.
