Don't call yourself "Christian" if you won't oppose people spewing hatred.

That was the challenge hurled by filmmaker Michael Moore to white American Christians, the bloc of voters that strongly voted for Donald Trump, catapulting him to the White House.

Interviewed on MSNBC's "AM Joy" show on Saturday, Moore called on Christians, white Americans in particular, to stand up for minorities and women who are coming under increasing attack from bigots since Trump stunned the nation with his Nov. 8 election triumph, Raw Story reported.

Following Trump's victory, Latinos, Muslims, African-Americans and women—people who strongly supported Trump's rival, Democratic Party's Hillary Clinton—have reportedly found themselves under attack from people spewing racism, causing many to fear going out in public.

"White people, no matter how painful, have a responsibility to reject anybody who stands in front of a camera who spews racism," Moore said during the show.

He said this is because white Americans comprise "the race that's been in power forever" in America.

The documentary filmmaker then specifically zeroed in on white American Christians. "Do not call yourself a Christian if you are not willing, literally, to put your body in front of whoever is coming to hurt the other — the people who are not you," he said.

According to Pew Research Center, 81 percent of self-identified white, born-again/evangelical Christians voted for Trump, while just 16 percent voted for Clinton. Trump's 65-percentage-point margin of victory among voters in this group – which includes self-described Protestants, as well as Catholics, Mormons and others – matched or exceeded the victory margins of George W. Bush in 2004, John McCain in 2008 and Mitt Romney in 2012.

Also on Saturday, Moore went to the Trump Tower in Manhattan in his attempt to personally confront Trump and tell him to resign, claiming that he did not actually win the election. He failed, however, after he was stopped by Secret Service guards when he reached the fourth floor of the building, the Daily Mail reported. Before that, he was with the thousands of people protesting against the President-elect outside the building.

Moore has vowed to help form a resistance movement against Trump.

In an interview with The Los Angeles Times, he said "it will be a mass movement of millions that will dwarf Occupy Wall Street."

"I don't believe anyone in the media who says we're going to have four years of Trump. This is a man who doesn't have any ideology; the only thing he believes in is Donald Trump. And that's usually a one-way ticket out of office," Moore said.
