Some of the country’s most prominent Hispanic and civil rights groups are heading to Rockefeller Center for a 6 PM rally today to protest Donald Trump’s upcoming hosting duties on Saturday Night Live. Just in time for the event, some 50 prominent Hispanic intellectual and cultural figures — including Birdman director Alejandro González Iñárritu and writer Junot Díaz — have distributed a letter denouncing the would-be Republican presidential candidate.

67th Annual Directors Guild Of America Awards - ArrivalsThe manifesto was posted on Univision’s website and also translated by Time magazine. According to the translation, it says, “We refuse to keep silent in the face of the alarming declarations of the candidate for the presidency of the United States Donald Trump. His hate speech appeals to lower passions like xenophobia, machismo, political intolerance and religious dogmatism. All of which inevitably reminds us of the past campaigns that have been directed against other ethnic groups and that have resulted in the deaths of millions of people. In fact, the physical aggressions against Hispanics and repeated calls to prohibit the public use of the Spanish language have already started.”

Trump first angered the Hispanic community during his June campaign launch, when he said some illegal Mexican immigrants were rapists and other kinds of criminals.

This evening, according to the National Hispanic Media Coalition, protesters representing groups including MoveOn, the Hispanic Organization Of Latin Artists, the Justice League and the National Association Of Latino Independent Producers will gather in front of the Comcast building at 30 Rockefeller Plaza for what’s being billed as an “SNL Dump Trump Rally.” Organizers say they will present NBCUniversal and Saturday Night Live executive producer Lorne Michaels with 460,000 signatures on a petition asking them to rescind Trump’s invitation to host the program this Saturday night.

On Monday, the Congressional Hispanic Caucus issued a statement that “calls upon NBCUniversal, Broadway Video, and SNL Executive Producer Lorne Michaels to disinvite Mr Trump from hosting Saturday Night Live because racism is not funny.”

During a book signing event on Tuesday, Trump mocked potential protesters in advance. “Oh, good, it will get even higher ratings,” he said of the show, according to a New York Times account. “It’s going to be one of the highest-rated shows ever.”
