it's simply the reality of current year. if you walk up to niggers on the street and call them niggers, there's a non zero chance that you'll end up getting assaulted, stabbed, or shot dead, and there will be minimal repercussions because the system does not want to protect people like you.
i'm not saying that you deserve to get assaulted for calling a nigger a nigger, i'm saying that if it happens and then you act surprised and outraged about it after the fact, then you're a bit of a dumb retard for not seeing it coming ahead of time.
