Yeppers! There are Un-PC minorities in the PC Universe! "Asian" is an Un-PC minority (I'd love to hear one of the Guardians of the PC Universe explain ton Japanese, Koreans, Chinese, Vietnamese, Khmer, Thai, etc. that they are all just Asians ... not sure if Indians are an Un-PC minority, yet).
I'm not sure if Jews are an Un-PC minority, or a Double-Plus-Un-PC part of the Un-PC "white" majority. But Jews are very Un-PC as well.
From my cynical vista point, the difference between a PC minority and an Un-PC minority - specifically, ethnic minorities - seems to be that Un-PC minorities are successful, and as such are evidence that the America-is-intrinsically-racist narrative is bogus.
