RE: Actually, your conclusion is based in a lack of critical thinking
Listen son, I have two black kids and decades of experience in the matter that shape my thinking. I will tell you without a doubt, if a grown white man uses the N word, they are in fact being racist. You might have an exception in academia or teaching, but that has probably gone the way of Mark Twain.
Providing a narrow definition on a vast subject full of intense history is quite the opposite of critical thinking. It’s lazy and ignorant.
