See how easy it is to call out a racist? People should start calling them out instead of pretending it's not an indication of a sick personality type.
I could not help but notice the heavy presence of alcohol, which may very well impair judgment and impact the tone of the discourse, but it certainly doesn't excuse it. The alcohol seems mostly to have "helped" in the removal of this "Ken's" personal self-policing function. Perfect opportunity to call him out and do a bit of public shaming.
