Terrorist Was Kind Of A Jerk

Omar Mateen was toxic, unhinged, unstable, racist, homophobic, prone to talking about killing people, and employed, prior to killing or injuring over a hundred people in Orlando.  A former co-worker left his job to get away from Mateen, and isn't at all surprised at what happened.  Their employer tolerated the man's offenses because he was Muslim, but don't you dare suggest he took up arms for the same reason.
