The paperwork follows the efforts of a George Washington University professor to revoke WWXX-FM’s broadcast license. John Banzhaf originally filed his petition last month, contending the FCC can take action against a broadcaster that airs the word because it is “akin to broadcasting obscenity” or that “it constitutes profanity.” Under current law, broadcasters face a fine of up to $325,000 per incident deemed indecent and could lose their licenses to operate.

Banzhaf said Tuesday that the addition of three Native American petitioners gives the case more standing because it shows that they have been affected by the use of the nickname.

“The interesting thing is that I’m no longer alone; I’m backed up by Native Americans. That should end any questions about whether or not there’s what we call legal standing,” Banzhaf said in an interview.

In an affidavit sent to the commission, radio host and petitioner Jay Winter Nightwolf states that he has “witnessed harm to myself and/or to other Native Americans which I believe was caused by the frequent repetitive use of the word “R*dskins” on the air.” Nightwolf hosts a show called “The American Indian’s Truths — Nightwolf” on WPFW-FM. The two other petitioners — Louis Ramon Grimaldi and Verona Iriarte — are producers of the show.

Banzhaf said that the new petitions bolster the argument that repeated use of the word constitutes hate speech and that it is a “fighting word.”

“Under Supreme Court precedent, fighting words do not enjoy constitutional protection,” he explained.
