I don't really think it's wrong to joke about Jewish people liking money, Albanians stealing, Americans being fat and Black people liking chicken. I make alot of these jokes with friends (multinational) and other people and they don't really mind and find it funny as long as I dont push it.
Joking for the sake of hating, and trying to put someone down however is a different thing and I don't think thats the case here. But if it was I'd agree with you Corsair. I do also believe that Jews get little more special treatment to racist jokes, because of the Holocaust. The Holocaust was a horrible thing but I dont see how that changes the fact that we can't make stereotypical jokes about Jews.
Little bit like that time my English teacher said it was wrong and bad for an author to have a person called "Jew" by others in a book, when in fact no one would give a shit if the person was called Christian, Muslim, Buddhist, The Australian, or whatever. Special treatment in my opinion.
P.S About the video, Corsair is right they are racist. A misconception amongst many is that immigrants can't be racist because they are immigrants. But they can. Some of the worst racism I've seen has been from immigrants (I'm an immigrant)
