> A system can be racist in terms of outcome without having been intentionally designed to be racist.
The problem with this line of thinking is it is so broad in its scope that it could literally be applied to anything where there isn't perfect uniformity of outcome. Just take out race:
> A system can be ___ist in terms of outcome without having been intentionally designed to be ___ist.
Consider these dubious outcome-based claims:
Classist: poor people don't own cargo ships, therefore the shipping industry is classist.
Sexist: spas attract more women than men, therefore the spa industry is sexist.
Racist: most Ethiopian universities have majority black student populations, therefore most Ethiopian universities are racist.
You get the idea. The question when assigning blame for ___ism shouldn't be What is the apparent outcome?, but What is the apparent intent? – and it's only fair to assume good intentions in others until proven otherwise.
