Pewdiepie forgot to call out the Anti-Semitic channel he popularized, he really doesn't handle Criticism well and Pewdiepie should know how big of an Influencer he is and he already should know more then anyone that he needs to be careful.
Pewdiepie and all the Youtubers seem to want Fame in the entertainment industry, If anybody in MSM did the same thing as Pewdiepie just did would they would be under similar scrutiny if not potentially worse.
Also Pewdiepie has turned into mostly a React Channel now he should know that he should do some research if he doesn't want Criticism from others as this is not the Only time he has made Controversy for something Anti-Semitic.
