It's absolutely common, but don't forget that this woman is a fucking racist piece of shit.

The Black National Socialist movement is now, and has consistently been, extremely racist for decades. Not just against white people, but also against jews, latinos, and asians. It's why anti-semetic hate crimes spiked in New York City, it's what's started gang wars in Los Angeles, it's why the black gangs attacked Korean store owners in the LA Riots. Black Supremacism institutionalizes the idea that blacks are inherently superior to all other races, and Black National Socialism promotes that all other races either oppress blacks, or ally with whites to oppress blacks. Even blacks who are slightly less black than other blacks are a possible avenue to White Supremacy.

These racialists want to see asians and jews get hurt or killed because they see them as an inferior race of off-whites that are oppressing blacks with the assistance of whites. She likes dead asians. Don't give her the credibility of being simply smug.
