The deadliest mass shooting in American history happened because of Islamophobia.
Islamophobia killed 49 people in Orlando. It didn't kill 49 Muslims. Instead it allowed Omar Mateen, a Muslim terrorist, to kill 49 people in the name of his Islamic ideology and the Islamic State.
Omar, like so many other Muslim killers, could have been stopped. He talked about killing people when he worked at G4S Security, a federal contractor that provided services to the Department of Homeland Security and the State Department. But, according to one of the co-workers he stalked, a former police officer, his employers refused to do anything about it because he was a Muslim.
