As a rule of thumb, it is not big news when multiple political rallies overlap on the same weekend in the nation's capital, a prime setting for anyone trying to send a message to the people in power.

But there are exceptions to every rule — and certainly an exception can be found in a large gathering of Juggalos airing a grievance against the FBI. (More on this later.)

On Saturday, downtown Washington, D.C. was home to three prominent demonstrations that some feared might combine violently but instead stayed largely separate and peaceful, with modest attendance.

The self-described Mother of All Rallies, designed to support President Trump and "defend American culture," was staged on the National Mall late Saturday morning.

Around the same time and several blocks away, near the White House, was the Protect American Democracy rally, which organizers say was meant to tell the president to take a tougher stance against Russian interference in American elections.

The rally garnering the most attention was the Juggalo March, an assembly set near the Lincoln Memorial of so-called Juggalos. The fans of the horror-core rap duo Insane Clown Posse are often adorned in face paint, tattoos and other symbols similar to those of the group. The march was described on its website as "a collective statement from the Juggalo Family to the world about what we are and what we are not."

Insane Clown Posse was founded in 1989, and despite criticism of the group's crude and sometimes violent lyrics, it developed a considerable and dedicated following of Juggalos. (The term derives from a 1992 Insane Clown Posse song, NPR's Tanya Ballard Brown reported.)

In a 2011 report, the FBI classified Juggalos as a "loosely organized hybrid gang" following violent incidents allegedly committed by fans of group. Juggalos, in tandem with the American Civil Liberties Union, sued the government in 2014, claiming Juggalos' "constitutional rights to expression and association were violated" by the FBI's classification. The case was dismissed but then later reinstated in September 2015.

And, according to the event website for the Juggalo March, the case has been thrown out for a second time, "meaning we are back to square one from a legal standpoint," the group says.

The case was dismissed both times by the same Michigan judge who said the Juggalos lacked "legal standing," The Guardian reports. The fan base will now have to wait at least six months for a ruling on the ACLU's second appeal, the newspaper adds.

The Juggalos say the gang label has, through unfair discrimination, made it difficult to live a normal life for many of their members, some of whom were scheduled to speak on Saturday as part of the effort to express their anger with the FBI.

"We are taking out [sic] fight to the streets. Literally," said a statement on the "Juggalo March" website.

As for politics, however, the "Insane Clown Posse and most Juggalos consider themselves very apolitical," pop culture writer Nathan Rabin told NPR's Scott Simon.

By the accounts of reporters from NPR and WAMU present on the National Mall, the crowds at all three events were enthusiastic but limited in size.

The pro-Trump Mother of All Rallies featured a float with signs saying "secure our borders" and "drain the swamp" and drew some prominent names from the so-called alt-right, including Jack Posobiec. The rally's organizers wrote on their website that Confederate flags and racism would not be allowed, clearly hoping to distinguish their event from the march of white supremacists that turned deadly last month in Charlottesville, Va.

Nevertheless, as NPR's Windsor Johnston reported, some counterprotesters attempted to tie the MOAR rally to Charlottesville, including one who held a sign featuring an image of the woman killed by a motorist there.
