The members of the Westboro Baptist Church have gone from protesting at funerals to basically protesting anything that will likely get them press. Their latest protest found them outside a Foo Fighters’ concert in Kansas City, Mo., Friday. According to members of the church, the group promotes “fornication, adultery, idolatry and [homosexuality]” with their music.

As have many before them, the Foo Fighters felt moved to respond.

Before their show, Dave Grohl and the Fighters rolled up on a flat-bed truck and performed “Keep It Clean (Hot Buns),” a song about intimate relations between two men. The fellas were dressed in the trucker costumes from the song’s music video.

“I don't care if you're black or white or purple or green, whether you're Pennsylvanian or Transylvanian, Lady Gaga or Lady Antebellum. It takes all kinds,” Grohl told the crowd, which included other counter-protesters.

While the Supreme Court ruled that Rev. Fred Phelps and his followers are within their constitutional rights to protest, the Foo Fighters showed that those who disagree with them will continue thinking of ways to fight back. Here are some of the most noteworthy counter protests the WBC has inspired:

The KKK : In one of the most bizarre free speech moments in recent history, members of the Ku Klux Klan picketed the WBC as they protested outside of Arlington National Cemetery.

I think “that it’s an absolute shame that [the WBC] show up and disrupt people’s funerals,” grand wizard Dennis LaBonte told CNN.

Angels of Peace : Dressed as celestial beings, the Angels of Peace were some of the first to protest Phelps and his church as they picketed the trials of the men who murdered Matthew Shepard because he was gay.

Bikers : When voices fail, roaring engines take their place. Biker groups have been called upon many times to use their motorcycles to drown out the sound of the WBC’s protests and create a kind of force field around their subjects. This tactic was used at the funeral of Elizabeth Edwards.

“If you want to protest a war, you do it with government officials, not with the soldiers who died for you,” Clyde Fleming, 62, said in October as he opposed the WBC outside of a Navy SEAL’s funeral. “You don't disrespect them and their families with such hatred.”
