An extremely unpleasant, hate-filled man has committed an awful, terrorist act. His social media has a lot of far-right, Islamophobic, conspiracy theory related hate in it. We should be united in condemning his acts and having compassion and respect for the innocent people whose lives have been lost or changed forever by his actions, rather than attacking each other and other minority groups.
I suspect he targeted a place he knew would be busy, filled with people who would not be able to defend themselves or fight back against him, because he's (like so many who try to commit such acts) a coward at heart. Utter scum.
