Our current hyper-partisan always-on tribalism is a fertile ground for witch hunts and rumors that go off the rails.

The Hispanic OK sign dude is one particularly egregious example of this. I think in most of these cases, the company thinks it's easier to fire the person than bother to investigate what actually happened.

So it's very important to verify that a so called "dog whistle" isn't a hoax or overblown, and sometimes even if some Internet trolls are trying to launch a dog whistle bringing attention to what they're doing is helpful marketing for their cause with all the attention it brings.
