I imagine there's more than a few freepers who are younger & may not realize how in previous generations (baby boomers or older) someone might reference a more prominent minority as an "uppity xxxxxxxxxx" (fill in the blank). IoW, in
their little mind, such a minority failed to be beholden to their supposed "assigned" socioethnic "placement" within society.
If any conservative had applied this adjective to a minority, it'd be front page news for weeks & months.
