Just because someone uses the "N" word, does not make them a racist. Anything can be a "N" word. I can call a tree the "N" word. The "N" word doesn't even have to be hateful. I can lovingly call my mother the "N" word.
I say "N" word because the boards censors the full word. Which goes to show how zero tolerance only increases the negative stereotype. It's right there in the phrase, "ZERO TOLERANCE".
I'm going to cut to the heart of the issue. The reason the N-word is treated with zero tolerance is because, if it were given a case-by-case basis of leniency (allowing it to be used colloquially in some cases, but banning it for being used hatefully in others), it would become needlessly harder to actually punish when it's used in hateful contexts, because then it would require further investigation to see if it was used by two people palling around, or by someone who wanted to berate and deride someone for something they had no choice in.
And this is ignoring whether or not people would generally be okay with it, even if it's used in a friendly manner. There are some black people out there who absolutely detest the word, even when it's used as a synonym for "friend" or "guy", and there are others outside of the targeted group who aren't okay with it either.
So should we just ignore the people who are put off by its usage, simply because the word's being used in a friendly context?
And on top of all of that, there are dozens of words you could use to refer to people with that haven't historically been used as hate speech. "Buddy", "guy", "pal", "friend", "dude", "man", "bro", etc. - Why use a word with a known historical background of prejudice when there are way more options on the table?
So basically, because some people were assholes HUNDREDS of years ago, present day people aren't allowed to use certain words. Even though, the culture has DRAMATICALLY changed. You think true racist people are using the same language for HUNDREDS of years? They moved on and created new words that aren't censored.
Racist culture may have changed, but what hasn't changed is the fact that the N-word is still used as hate speech. If racist culture has moved on, they haven't moved very far at all.
And, like I said, it's not like we don't have any other word to use.
Banning a word does not alter a persons personality. True racist people are going to think racist thoughts no matter how much you ban their language.
So, what? Because some people will remain adamantly racist no matter what, we should just accept it and let them do their thing?
If they want to be racist and vile, they can do it elsewhere. Riot's made their stance clear - they don't accept racism, and they're ready and willing to show any racists who happen to display their true colors to the door.
