The leader of an atheist group behind banners displayed in Fort Worth says she's not concerned that the message may upset people.

The yellow banners, which read "In No God We Trust," are meant to promote an event Metroplex Atheists is holding later this month. Courtney Stewart, 29, the group's president, said she knows the meeting may also draw people who are angry about the banners.

"The point of this entire campaign is to bring attention to this issue and give a voice to a minority viewpoint," she said. "The more people that show up, positive or negative, it's part of creating that conversation."

Fort Worth Mayor Betsy Price tweeted out her dislike of the message Tuesday after the city received complaints.

"I was appalled when I saw the banners currently being displayed downtown, as I do not support or agree with the message," Price said on Twitter. "We must respect freedom of speech. As we approach the Fourth of July, we must remember that many Americans have fought and died for the freedoms we cherish today."

The banners advertise an "educational seminar" about amending the nation's motto to E Pluribus Unum, a Latin phrase meaning "out of many, one."

"'In God We Trust' painted America as a Christian nation, which is incorrect," Stewart said. "The point of the banner is to argue against this false rhetoric that is divisive and dangerous, that calls non-religious people un-American and people who fall outside the Christian narrative un-American."

In a written statement Tuesday, the city said Metroplex Atheists followed the rules to display the banners.

"While some residents might not like the messaging on these banners, we do not currently restrict religious messaging, as long as it follows the current policy and procedures for displaying banners," the statement said.
