Mord,
If someone said to you 'Jews are cheap bastards' would you immediately assume they are talking about the liberal Jews only? If so you are exhibiting naivete. When the nazis said they wanted to round up all the Jews and burn them in ovens a lot of Jews thought 'Hey, they are talking about THOSE Jews, you know, the ones with the big hooked noses.... But us hard working Jews, they don't want to annihilate us.'.
It is that kind of stupidity which led a lot of righteous Jews into the ovens.
