Cantonese grannies get beat up by (mostly) blacks because of legacy of miscommunication and cultural divide between the black and Asian community, further accentuated by pandemic-related high unemployment, alcohol/substance abuse crisis, mental health crisis, and Trump's incendiary anti-Asian rhetoric and blaming Chinese.
Atlanta is very liberal city (not conservative) but they are a blue dot in a sea of red (Georgia). The white shooter dehumanized and victim-blamed Asian massage parlors as sex workers, and murdered them in religious quest to eliminate his lustful sins. (Total bullshit). I can't explain crazy looney white shooters and lonely white shooters are a dime a dozen. I blame religion and mental health rather the political ideology.
