A heated battle broke out at the Proud Boys sedition trial on Monday over an internal "initiation ceremony manual" that the federal government wants to show to jurors, but which a defense lawyer says is too "politically incorrect" to be in evidence.

The manual was seized by the government via search warrant two years ago, but was only just made public, according new court papers filed in the US District Court trial in Washington, DC.

Prosecutors in the case allege that five men who were Proud Boys leaders conspired to violently storm the Capitol on January 6, 2021 to block Congress from certifying the results of the 2020 Presidential election.

The recently revealed manual details how a Proud Boys chapter leader must run the group's meetings, or "meet ups." It includes the language for calling meetings to order and a required reading from Pat Buchanan's "The Death of the West," which calls on "Western Man" to stop apologizing to "race racketeers" about slavery and colonization.

The Anti-Defamation League considers the Proud Boys a violent, right-wing extremist group whose members commonly engage in misogynistic, Islamaphobic, transphobic, and anti-immigration rhetoric.

The manual instructs Proud Boys on the wording of such drinking toasts as, "To guns," "To housewives," and, "to the greatest civilization on earth and the men who built it."

It describes the extremist group's politics, including a commitment to "rebuilding the patriarchy" and a belief that, "All other cultures are not merely different than us. They are worse."

Oddly, the guide also includes the lyrics to "Proud of Your Boy," a heartfelt solo by the title character from the Broadway musical "Aladdin." In the ballad, Aladdin seeks his mother's approval.

Apparently, the Proud Boys consider the ballad "our anthem."

"It is healthy to sing our anthem at least once a night but this isn't always possible," the manual tells novice Proud Boys leaders before helpfully supplying the words for a rousing sing-along.

"Ideally, we seek out venues that have a jukebox with this song available," the manual advises.

But as proud as the defendants may be of their rituals, a defense motion seeking to bar the manual from being shown to jurors acknowledges that many would find it repulsive.

"The document is riddled with politically incorrect remarks and assertions which would cause most or many Americans to recoil in anger, hatred and disgust," wrote Roger I. Roots, attorney for defendant Dominic Pezzola.

"The document is bizarre and humorous in some places, and intensely politically incorrect in others," wrote the lawyer for Pezzola, who is accused of using a forcibly-stolen Capitol Police riot shield to break the first window into the Capitol.

Pezzola's motion complains that the manual is unsigned, unauthenticated, undated, and, ultimately, irrelevant. Lawyers for the Department of Justice have countered that the its 11 pages demonstrate Pezzola's knowledge and state of mind while at the Capitol.

Details of the Proud Boys' beliefs and membership requirements — including their so-called "fraternity creed" — have been made public before, including on their websites and during political campaigns.

But the "initiation ceremony manual" released Monday appears to be the first airing of an an internal, "How to" for running a Proud Boys meeting.

The manual veers wildly among topics, at one point giving meticulous dress advice — "a recommended shoe is the black Red Wing classic moccasin toe boot" — in the same paragraph as it vows "This is about taking our civilization back. This is about rebuilding patriarchy."

But the first four pages stick to how to run a meeting, including this requirement: "Before the meeting begins, clear the area of all women" and of all non-Proud Boys.

Two guards are to monitor "the perimeter," the manual instructs, as the "brother in charge" leads the meeting with a series of recitations and "toasts," including, "to the housewives that create human life, shape it, and build the communities in which we live."

The final toast is more of a threat.

"To the parasites both on the streets and in the White House who want to attack us and take what we earn," it begins. "To the trespassers who want to attack us and take what we earn. To the trespassers who want to sabotage our culture our family and our way of life.

"You want a war?" it continues. "Well, you've got one. To all of our enemies both high and low."

At that point the Proud Boys members are to shout, "Bring it on!"
