Because the issue isn't racist depictions. It's a lack of education and a focus on intolerance instead of actually employing the sympathy you are demanding. Nobody is arguing the word or imagery is fundamentally racist in origin. We're saying they honestly don't know about that so need education. That's the context you are ignoring to go on your black knight crusade.

You are the exact opposite of what the Peace Corps is asking their members to be. Hear the offensive word and you go on a rage fueled violent rant about how racist they are being instead of taking a deep breathe, looking at the situation and realizing they only use the word because it is the only one they know. Simply taking the time to inform them of how hurtful the word/imagery is without being a salty bitch about it is how fences are mended.
