We're all ignorant to some extent. I believe us as a generation say the n word way to much, and that makes us ignorant, however it's just the common thing to say among most friend groups despite race. I believe about 1% of the use of the word is racial, and especially with it ending in an "a" but I believe it is less acceptable as the version ending in "er".
I don't believe "a" should ever justify an ass whooping or harsher, or even considered racist unless under extreme circumstances, and I personally believe African Americans WHO SAY THE WORD COMMONLY are bigoted, hypocritical, and ignorant when they take offense to a white person(or any other person) who uses it in the same way.
