Some people have no sense of humor.
Try being a German-American in a post WWI & WWII world. Lots of chances to mimic the gutteral Germanic language and Herr Hitler. Some of the things have humor, but others are so stupid, you would think folks believe Germany had no history before 1934.
Try to look up German history in a library or on the internet, and the first 10,000 hits are about Nazis.
But, that’s not the worst of it. The stupid liberals in Hollywood are still making movies about terrorists and depicting them as neo-Nazis (German types) - never once do they depict terrorists as Middle-Easterners with Islamic ties. And, these folks get off the hook by the media who depict them as “Asians”.
Back to round one. Maybe the Asian caucus ought to be offended that Islamic terrorists are lumped in with their more peace-loving group - and leave Rush out of it. Go after the MSM, if you really want to be offended.
