Not all billionaires think alike.
Just two days after presidential hopeful and notorious billionaire business mogul Donald Trump infuriated people with his suggestion that the U.S. implement a “total and complete” ban on Muslims entering the United States, Facebook CEO Mark Zuckerberg is speaking out in opposition.
In a Facebook post Wednesday afternoon, Zuckerberg doesn’t address Trump specifically, but leaves little doubt as to who and what motivated his comments.
“As a Jew, my parents taught me that we must stand up against attacks on all communities. Even if an attack isn’t against you today, in time attacks on freedom for anyone will hurt everyone,” he wrote. “If you’re a Muslim in this community, as the leader of Facebook I want you to know that you are always welcome here and that we will fight to protect your rights and create a peaceful and safe environment for you.”
Facebook has more than 1.5 billion people on it every month, making it the most populous destination anywhere — online or in the real word. It’s larger than China or India and more than four times larger than the U.S.
Trump’s initial comments were proposed as a way to combat acts of domestic terrorism like the recent attacks in San Bernardino, Calif. He believes the ban on Muslims is necessary “until we are able to determine and understand this problem and the dangerous threat it poses.”
The remarks left plenty of people upset. Trump has been roundly criticized for the remarks, even by those from within his own party.
“Some of our best and biggest allies in this struggle and fight against radical Islamic terror are Muslims, the vast, vast, vast majority of whom are people who believe in pluralism, freedom, democracy, individual rights,” House Speaker Paul Ryan told the New York Times.
