I don't think he's literally a Nazi, but jokes about him being a Nazi/white supremacist aren't completely unwarranted, given what he's said recently. He's the face of YT, he can affect the whole of YT, and he has. A LOT of channels are losing money and some have been demonetized completely because of the change in ad revenue brought on by the video you linked. And to have such an effect on so many others, I'm perfectly fine with the consequences he suffered because of it.
But despite all that, a lot of people forgave him because it was supposed to just be an edgy joke that fell flat. The new incident, however, just totally blows my mind, with the explanation that it was just a "heated moment," and people are actually defending him. I'm a white guy in the South, and I've never heard that word spoken by a white person out of sheer frustration. No one hits their thumb with a hammer and screams "Spic!" It's absolutely ridiculous.
I personally don't like his videos, either. I saw an Amnesia video and it was just him screaming and making rape jokes, then I was done. I don't think he's necessarily a bad person, but I'm not losing any sleep over him making piss-poor decisions.
