Aggregating everything and taking an average doesn't prove 'everything is racist', it just proves some portion of people are. It's not traffic stops, 'the police', or 'the system' that is racist, it's individual cops making the decision to pull over one person and not another. If this were an example of systemic racism, there would be a systemic fix, but there isn't. The only way to fix this would be to wipe out or even out the biases of the individual officers. Police departments in the bay area are very ethnically diverse: https://www.nbcbayarea.com/news/local/do-bay-area-police-dep...
The claim they were contesting was that the poster couldn't find "a single example of systematic racism". Countering that doesn't require that every single person isn't racist, just that racism exists and has a measurable impact.
> Institutional racism was defined by Sir William Macpherson in the UK's Lawrence report (1999) as: "The collective failure of an organization to provide an appropriate and professional service to people because of their colour, culture, or ethnic origin. It can be seen or detected in processes, attitudes and behaviour that amount to discrimination through prejudice, ignorance, thoughtlessness, and racist stereotyping which disadvantage minority ethnic people."
If you define any amount of discrimination as a failure to provide an appropriate professional service, then, mathematically, any amount of racism will become 'systemic' or 'institutional' so long as there is an uneven population distribution:
Let's say there are 3 groups. One group is 60% of the population, another is 30%, and the last is 10%. If all three groups have the exact same predisposition to favoring members over outsiders, the 60% group will experience prejudice from 40% of the population. The 10% population will experience it from 90% of the population. The 10% group will experience >10X the incidence of prejudice unless group favoritism is <= 0, which is literally impossible.
If that's what you mean when you say systemic/institutional, it feels like a completely useless thought to me. I, and I think many other people, hear 'systemic', and think 'coming from processes, rules, or procedures defined as part of a system', not from the people operating it. To make a better analogy, when I hear systemic car problem, I think the engine, transmission, or some other component of the car, not the driver.
