Indications are this latest atrocity may have been a manifestation of religiously motivated terrorism.
Hopefully our thought leaders and intellectual betters such as Barack Obama don't try to PC around this by attributing it "workplace violence" or "mental illness".   Or try to equate the perpetrators with the victims such as Donald Trump attempted after the attack by a neo-Nazis in Charlottesville.  Or try to excuse the actions of the terrorists because they "felt excluded" as Justin Trudeau attempted after the Boston Marathon attack.
It's all bad.
