You weren't supposed to actually implement it, Google

Last month, I wrote a blog post warning about how, if you follow popular trends in NLP, you can easily accidentally make a classifier that is pretty racist. To demonstrate this, I included the very simple code, as a "cautionary tutorial". The post got a fair amount of reaction. But eventually I heard from some detractors. Of course there were the fully expected "I'm not racist but what if racism is correct" retorts that I knew I'd have to face.
