Double Standard When is It ok?

just got home and turned on the tv, and after flipping through the channels for about 20 minutes i’ve noticed something and was kinda bothered. within those 20 minutes ive heard the words cracker, jew, chink, beaner, dumb spik, and every derogatory racial slur you can imagine. the question i ask is why is it ok to say all these words on television? But the moment a person that is of no color say the word nigger or black person or even use the word ghetto is applied its wrong. why is it wrong? the jews were slaved the japanese were slaved the indians were slaved but i dont ever see any white,  japanese or any other race protest or get angry if a the words craker chinky eyed or any racial slurs are used on national TV or movies. so the real question is what racial words are ok to say? I’m sure you guys are gonna respond and say its never ok to say any racial words. but honestly think about it. you yourself have used these words wether it was a joke or out of madness but the moment we say nigger its wrong WHY?
