The "Nazi Soup" episode was first aired in 1995, nearly a quarter of a century ago. In 2018, anti-semitic assaults nearly doubled in this country. Three months ago, Germany government officials told Jews not to wear kippa caps in public because of the rise of anti-jewish attacks. They are once again being physically attacked simply for their race/religion.
Most Jews, like rednecks, make so much fun of themselves, they really don't care if the rest of the world joins in. It's been my privilege to be both. I think people who get offended at every little thing show they are insecure with who and what they are.
The "Nazi Soup" episode almost certainly wouldn't have been written and aired now. It wouldn't be appropriate now.
