Earlier quoted context omitted.
I didn't downvote you, nor am I a fan. I only saw parts of the episode when a friend watched it, so I did not see it in it's entirety. Is what you listed a complete listing of things he attempted to get through? Or just your selection of what he tried that was prejudice? It seems likely he also would have tried to get some other dumb things through on the level of dick jokes.
Do we really need the complete list of things he said before we can judge the wisdom (or lack thereof) of the headline-grabbing ones? "Is what you listed the complete list of ingredients to this homeopathic medicine? Or just your selection of the poisonous ones? It seems likely they would have put in some other healthy things on the level of ginseng"
In this case, if the list contains mild things and racism, then its probably just that PewDiePie is racist. If the list contains nothing socially acceptable and some of it happens to racist well then clearly the whole thing was for shock value, and the racism was probably just a way to push your buttons.
