Public schools in South Dakota must have the “In God We trust” motto on display at all times now due to a new state law — which is meant to “inspire patriotism.”

“Some have plaques. Others have it painted on the wall, maybe in a mural setting,” explained Wade Pogany, executive director of the state’s Associated School Boards.

He told reporters this week that educators have already started complying with the new law, which went into effect earlier this month after being approved by Gov. Kristi Noem back in March.

The Freedom From Religion Foundation on Thursday blasted the legislation as a “stealth campaign” — meant to force religion onto residents and into state politics.

“Our position is that it’s a terrible violation of freedom of conscience to inflict a godly message on a captive audience,” the organization said in a press release.

The group is also against the government’s use of the “In God We Trust Motto” on US currency, which started in 1956 and was approved by President Eisenhower.

“These laws are about advancing the Big Lie that the United States was ‘founded on God’ or Christianity, thus dismantling the wall between religion and government,” said FFRF officials. “The motto “In God We Trust” is inaccurate, exclusionary, and aimed at brainwashing American schoolchildren into believing that our nation is a theocracy.”
