"No, it hasn't. Why would one single person using a racial slur used by millions a day be on the news?"
Yes, it has. https://www.bing.com/search?q=shiloh+hendrix&form=ANNNB1&refig=4a3ef269ddf0484bad0353626b6ef60b&pc=ASTS&adppc=EDGEXST
There's a reason people are talking about it and why a simple Google search will bring up her name and have multiple articles talking about it. If you refuse to follow the link (since you claimed, you refuse to follow links provided) just google Shiloh Hendrix.
"No, you are the one concerned about it. Hence your reaction."
You think I'm concerned about what, exactly? I couldn't care less if she used the n-word. Just as I couldn't care less when a black person uses racial slurs against me.
"He not only did not defend him, he didn't even mention him."
By deflecting away from the part of the meme that references the black teen who murdered the white teen by stabbing him in the heart, it tells me he either condones it or he's trying to make it less of an issue than a racial slur.
And to answer your question about why I'm not using the n-word here it's because 1) I don't use slurs in public so I don't use them online and 2) because if I did use it here, I would be banned for a week from posting anything.
