Piwdiepie should actually sue WSJ for this. It's slander.
Anyone who has watched his show, and people like me who just started watching for the first time to see what was going on under the "scandal", can see that pewdiepie clearly is not anti-semitic or racist for that matter. He acted insensitively by treating nazi imagery so lightly, which was probably wrong, but that's a long way from holding anti-semitic beliefs and promoting anti-semitism. The meaning of anything cannot be separated from context to be accurate.
I've actually lost all respect for WSJ now. I used to think they were a highly credible paper/site.
Also, the I KILL HITLER! episode was both hilarious and the perfect response. Made WSJ look like the fools they apparently are.
I guess he makes an easy target looking the way he does, but that in itself is the definition of prejudice.
