Hello Everyone! #DictatorErdogan @RTErdogan thugs attacked and threatened me today after Friday prayer in Boston at a mosque Turkish Government don't even let me practice my religion freely in America let alone my freedom of speech is under attack @FBI @FBIBoston @bostonpolice https://t.co/FH2Ixe6QcY
Kanter and rookie teammate Tacko Fall visited the mosque following the Celtics' first practice of the day. Kanter said that as he and Fall attempted to leave, two men began "screaming" and "cursing" at him, per Bontemps:
"It was pretty crazy, because this is America. You should be safe to come in a mosque and pray peacefully. It was the first time it's happened to me in America, but it was definitely scary because I looked at Tacko and said, 'Tacko, don't worry about it. I've got it. We're fine.' But we were just waiting for our Uber, so it was crazy and scary."
He said Saturday he won't allow the situation to stop him from speaking out against Erdogan, per Nicole Yang of the Boston Globe:
"No, what I'm doing is huge because I'm talking about human rights. I'm talking about democracy, freedom, freedom of speech, religion, and expression. I'm talking about justice.
"So, just because I'm talking about these issues and that stuff, I'm going to get threats? I'll take that. I'll be OK having security next to me 24/7. But those issues that I'm talking about are way bigger than myself and basketball."
Kanter has long opposed Erdogan.
In May 2017, he called Erdogan the "Hitler of our century" as he was being held at a Romanian airport after Turkish officials canceled his passport.
Mike Vorkunov of the New York Times reported that December that the Turkish government wanted to imprison Kanter for a minimum of four years for insulting Erdogan.
In June 2018, the Turkish government sentenced Kanter's father, Mehmet, to 15 years in prison.
As a member of the New York Knicks, Kanter declined to go with the team to London last season. He revealed in January he can't travel outside of the United States and Canada because "there's a chance I could get killed out there," referencing Erdogan, whom he called a "maniac."
Kanter signed with Boston as a free agent in July.
