Amanda Blackhorse is a social worker and member of the Navajo people who is known for her work as an activist on the Washington Redskins name controversy. She is the lead plaintiff in Blackhorse v. Pro-Football, Inc.
At an NFL game in Kansas City, "people yelled, 'Go back to your reservation!' 'We won, you lost, get over it!' 'Go get drunk!' And so many different slurs … I've experienced racism in my lifetime, but to see it outwardly, and nobody did anything?"
Blackhorse v. Pro-Football, Inc.
Blackhorse is the lead plaintiff in Blackhorse v. Pro-Football, Inc., which seeks to revoke trademark protection of the term "Washington Redskins". The USPTO rejected an application to register "Redskins Hog Rinds" because it "consists of or includes matter which may disparage or bring into contempt or disrepute persons, institutions, beliefs, or national symbols". Since 1992, the USPTO has rejected eleven applications for other trademarks that included the word redskins, based on the same reasons. Some of the applications were made by Pro-Football, Inc., including "Washington Redskins Cheerleaders".
On June 18, 2014, the Trademark Trial and Appeal Board (TTAB) of the United States Patent and Trademark Office (USPTO) voted to cancel the six trademarks held by the team in a two to one decision that held that the term "redskins" is disparaging to a "substantial composite of Native Americans", and this is demonstrated "by the near complete drop-off in usage of 'redskins' as a reference to Native Americans beginning in the 1960s."  In a press release the trademark attorney for the team stated that they were confident that they would once again prevail on appeal, and that today's decision will make no difference in the continued use of the Redskins name.
Plaintiff Amanda Blackhorse said in an interview, "We’ve been through this process for eight years now. We will continue to fight. And, you know, this is not the end for us."
It is likely that Amanda Blackhorse has lost her bid. Supreme Court rules ban on offensive names is unconstitutional, even though the vast majority of native Americans do not find the term "Redskin" as disparaging or offensive.
