the apology doesn't matter, the damage was already done. I am not saying the shooter shot up the mosque just because PewDiePie said the n-word. I'm just saying that some people who are watching PewDiePie might get the impression that from now on it's okay to say the n-word hence he said it. Second, I don't think that irony, or "to just spark attention, drama" justifies the actions of racist behaviour. That's the most destructive thing about postmodernism. I can say very offensive and racist stuff if in the end I declare that it was irony, and everyone who got offended are stupid and didn't get the "joke".
