LAFC and its supporters' union have condemned the anti-gay, Spanish-language chant that was heard during the inaugural match at the new Banc of California Stadium on Sunday night.
The club and its 3252 Independent Supporters Union said in a joint statement on Monday that they do not "condone the use of offensive language and inappropriate chants" and that they "have no place at Banc of California Stadium and within our club."
The chant, which occurred during goal kicks from LAFC's home-opening opponent the Seattle Sounders, has also been a divisive issue in games featuring the Mexico national team.
"The offensive goal kick chant is wrong and not what we are about," the statement said. "We ask that all of our fans and supporters work to hold each other accountable to eliminate this from Banc of California Stadium."
The statement also went on to say that "any fans identified as participating in this offensive chanting will be removed from the stadium and the club will revoke their season membership."
The chant, which translates as "male prostitute," was first popularized in Mexican stadiums and, after being heard on the global stage at the 2014 World Cup in Brazil, spread to fans of some other countries in the Americas.
FIFA fined Mexico's football federation over the chant in all eight of the national team's home qualifiers for the 2018 World Cup, though the Court of Arbitration for Sport later threw out the $160,000 in penalties because it said the governing body had created the understanding that those cases would not be punished.
Mexico's appeal said that while the chants used "insulting words," fans did not say them with an intent to offend. However, the court said in its verdict that the words "could still be considered discriminatory or insulting in nature and should not be tolerated in football stadiums."
LAFC, Major League Soccer's newest expansion franchise, went on to win its home opener 1-0 thanks to a late goal from a free kick by captain Laurent Ciman.
MLS commissioner Don Garber, who was in attendance on Sunday, said at halftime of the game that the league will not tolerate the chant.
"It shouldn't happen, and it will stop," he said. "We are not just concerned about it. It defies everything we stand for. I've spoken to ownership during the game. They get it. And I have real confidence that it'll stop."
