So you still think Black people should be given special treatment and be allowed to keep using the word? That's treating Blacks differently, because they're black. That's Racism pure and simple.
Some do describe racism as any observation of the differences between the races. People who don't understand affirmative action, or Stephen Colbert for instance, when he's trying to highlight the absurdity of that logic.
I think that any intelligent person knows that racism (in the true meaning of the word as used in the everyday vernacular) is usually defined as:
Racism is usually defined as views, practices and actions reflecting the belief that humanity is divided into distinct biological groups called races and that members of a certain race share certain attributes which make that group as a whole less desirable, more desirable, inferior, or superior.
Special treatment for using a word? Is this high school? Is it something that you really want to, or have to say? Does it somehow make the white race less desirable or inferior for not being able to use that word without offending someone, and the black race more desirable or superior because they can without offense to themselves?
This, however, has nothing to do with the racial attributes, similarities, or differences of the black or white races. You could interchange blacks with any race, and whites with any race, and it wouldn't change the context of this argument. This is a sociological phenomena, and would be true of any race of people that were forced into slavery for hundreds of years by one race, believed to be less than human (3/5ths) by that race, treated less than human by that race, and had certain demeaning words used to denote their difference as a non-human or less than human by that race.
You walk around using the "N" word and not being a racist... I'll be content to not use the word and have people like you think that I'm a racist
