Okay, how about putting your sarcasm aside for a second and asking yourself where those metal shavings came from. They didn’t just manifest there all by themselves, you know. Someone must have been working nearby, drilling a hole or whatever, and simply forgot to clean up after themselves, because they didn’t think it was important.
Now, that COULD have happened to anybody, but when all of SJW Twitter, and even the National Museum of African American History have been informing us for the past five years that things like being competent at your job, having attention to detail, following rules, etc. are all symptoms of whiteness and therefore racist, it paints a certain picture of the most likely candidate, doesn’t it?
