The hashtag #ChangeTheName has been a popular way for Twitter users to express their displeasure with the American football team, the Washington Redskins.
This weekend the protest went offline and into the streets.
More than 3,000 people demonstrated in Minneapolis on Sunday outside the team's game against the Minnesota Vikings.
It was billed by organisers as the largest rally to date against a name and a mascot that is offensive to many Native Americans.
The team's owner Daniel Snyder has vowed not to change the name or logo, saying that it honours Native Americans and their culture. He has sued five Native American activists who seek to have the team's trademark revoked.
Tweets, photos and status updates featuring #NotYourMascot, #NoHonorInRacism and #ChangeTheName were posted more than 24,000 times on Sunday.
The BBC's Franz Strasser talked to protesters at the rally in Minneapolis.
No Redskins fans approached at the game wanted to be interviewed on camera.
