Michael Moore stood outside New York’s famous Trump Tower yesterday in protest of its namesake’s recent controversial comments regarding Muslims.

His message to Donald Trump? “We are all Muslim.”

The liberal Michigan filmmaker explained why he was calling out the GOP presidential front-runner in a letter posted on his website.

Moore begins the post by recounting their first meeting in November 1998 backstage at a talk show, during which he says he left thinking, “‘What a wuss.’”

Here’s an excerpt of his open letter to Trump:

“Here we are in 2015 and, like many other angry white guys, you are frightened by a bogeyman who is out to get you. That bogeyman, in your mind, are all Muslims. Not just the ones who have killed, but ALL MUSLIMS.

Fortunately, Donald, you and your supporters no longer look like what America actually is today. We are not a country of angry white guys. Here's a statistic that is going to make your hair spin: Eighty-one percent of the electorate who will pick the president next year are either female, people of color, or young people between the ages of 18 and 35. In other words, not you. And not the people who want you leading their country.

So, in desperation and insanity, you call for a ban on all Muslims entering this country. I was raised to believe that we are all each other's brother and sister, regardless of race, creed or color. That means if you want to ban Muslims, you are first going to have to ban me. And everyone else.

We are all Muslim.”

Moore said he stood outside Trump Tower until he was asked by police to leave.
