I’ve never seen the show. I was just answering the question posed more generally about Asians.
I’ve spent a lot of time in Asia on business and this may be a stereotype more well known within Asia. More than a few times I’ve had a Chinese client or colleague find out I was Jewish and then the mutual teasing comes out. A lot of Chinese see themselves as the “Jews of Asia” for a number of cultural reasons but that’s a topic for a different thread.
I’m a minority Seattlite, and the professional “class” is even whiter, with a healthy dose of Asian thrown in. It’s also probably the least black big American city I’ve ever been. Frasier did not surprise or offend me at all demographically [well OK, Daphne should have been a Latina].
