After John Taggart fell in the pool he changed into dry but very "Jewie" clothes.
The vibe I got was that the clothes looked more like something an anti-Semite might wear. I'd guess you have a similar wardrobe.
The sequence with Jewish Sidney Bernstein was very anti-Semite. Extorting him for Jew money. Making him look like a total dweeb. Making fun of Jews.
The homeowener was Richard Tienken and he was Jewish.
