I didn't read anything that said the suicide had to be intentional.
The rate of Whites/Non-Hispanics dying from overdoses is 26.2, and the rate for Non-Hispanic Blacks is 24.8.
So, it would appear Whites and Black commit suicide in close to even rates. But, add in other minorities:
Non-Hispanic Native American/Alaska Native: 30.5
Non-Hispanic Asian: 3.3
Non-Hispanic Native Hawaiian or Other Pacific Islander: 9.5
Hispanic: 12.7
Those rates are per 100,000 Standard Population.
Yeah, I'd say suicide has a preferred race. When you look at factors like racial division, messaging that says you're oppressed by Whites, Critical Race Theory training, lower quality healthcare, need to work longer hours for less pay in some areas, poor educational opportunities, substandard public schools in urban areas, Social Media flaunting the good life that most will never achieve, ....it's a wonder most people below a given economic level aren't suicidal.
