American documentary filmmaker, screenwriter, author, journalist, actor and political activist Michael Moore stood in front of Trump Tower Wednesday with a sign that read "We Are All Muslim," hoping to initiate what he considers to be a solidarity campaign. He is asking people to sign a statement and share a photo of themselves holding the same type of sign. He has nearly 1.4 million friends on Facebook and 1.9 million followers on Twitter. 

GOP presidential candidate Donald Trump evoked outrage from across the political spectrum on Dec. 7 by calling for a "total and complete shutdown" of Muslims entering the U.S., a proposal the Wall Street Journal indicated "taps into voter anxiety about the recent spate of terrorist attacks yet likely runs afoul of religious freedoms enshrined in the Constitution."

Moore's new statement reads:  "Dear Donald Trump, 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. Just as we are all Mexican, we are all Catholic and Jewish and white and black and every shade in between. We are all children of God (or nature or whatever you believe in), part of the human family, and nothing you say or do can change that fact one iota. If you don't like living by these American rules, then you need to go to the time-out room in any one of your Towers, sit there, and think about what you've said. Signed, Everyone"

Moore, 61 years old and known to be a staunch Democrat, said he held in the sign at Trump Tower until the police came. Then he went home and penned the following letter to Donald Trump.

"Dear Donald Trump:

You may remember (you do, after all, have a "perfect memory!"), that we met back in November of 1998 in the green room of a talk show where we were both scheduled to appear one afternoon. But just before going on, I was pulled aside by a producer from the show who said that you were "nervous" about being on the set with me. She said you didn't want to be "ripped apart" and you wanted to be reassured I wouldn't "go after you."

"Does he think I'm going to tackle him and put him in a choke hold?" I asked, bewildered.

"No," the producer replied, "he just seems all jittery about you."

"Huh. I've never met the guy. There's no reason for him to be scared," I said. "I really don't know much about him other than he seems to like his name on stuff. I'll talk to him if you want me to."

And so, as you may remember, I did. I went up and introduced myself to you. "The producer says you're worried I might say or do something to you during the show. Hey, no offense, but I barely know who you are. I'm from Michigan. Please don't worry -- we're gonna get along just fine!"

You seemed relieved, then leaned in and said to me, "I just didn't want any trouble out there and I just wanted to make sure that, you know, you and I got along. That you weren't going to pick on me for something ridiculous."

"Pick on" you? I thought, where are we, in 3rd grade? I was struck by how you, a self-described tough guy from Queens, seemed like such a fraidey-cat.

You and I went on to do the show. Nothing untoward happened between us. I didn't pull on your hair, didn't put gum on your seat. "What a wuss," was all I remember thinking as I left the set.

And now, 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.

Just as we are all Mexican, we are all Catholic and Jewish and white and black and every shade in between. We are all children of God (or nature or whatever you believe in), part of the human family, and nothing you say or do can change that fact one iota. If you don't like living by these American rules, then you need to go to the time-out room in any one of your Towers, sit there, and think about what you've said.

And then leave the rest of us alone so we can elect a real president who is both compassionate and strong -- at least strong enough not to be all whiny and scared of some guy in a ballcap from Michigan sitting next to him on a talk show couch. You're not so tough, Donny, and I'm glad I got to see the real you up close and personal all those years ago.

We are all Muslim. Deal with it.

All my best,

Michael Moore

P.S. I'm asking everyone who reads this letter to go here and sign the following statement: "WE ARE ALL MUSLIM" -- and then send post a photo of yourself holding a homemade sign saying "WE ARE ALL MUSLIM" on Twitter, Facebook, or Instagram using the hashtag #WeAreAllMuslim. I will post all the photos on my site and send them to you, Mr. Trump. Feel free to join us."

Moore is known for satire, and his debut film was "Roger & Me" became the highest-grossing American documentary of the time.

One of Moore's Facebook friends, Jill Kelly-Moore, garnered more than 2,400 likes for the following comment in response to Moore's initiative:  "Trump is the proof that money will not buy class, conscience or common sense." 

Moore said he will post the photos on his website and send them to Trump. 

Allen Mortham Jr. on social media Thursday posted he finally after many years had found something with which to agree with Moore:  "That is that Trump is a delusional idiot! I don't agree that we are all 'Muslims' but I also don't think that all Muslims are a bad, in fact the vast majority of them are probably hard working people. We can't be scared of people who are different from us. That is NOT what this country was built upon! We are and always have been the melting pot of freedom. Just think if all those years ago when people (Americans) were afraid of the Irish, Italians, Japanese etc. etc. had wanted to exclude them from coming to the USA, where we would be now? Trump is just a sad, scared old man! If you wanna exclude people, go after the criminals in every race, religion and creed, then we'd all be better off!"
