Updated at 1:31 p.m. to include comments from The Satanic Temple spokesman.

The Satanic Temple doesn't like the paddling of schoolchildren, so it's picking a fight with a small Fort Worth-area school district.

On Wednesday, it raised a billboard along State Highway 199 in Springtown with this message: "Never be hit in school again. Exercise your religious rights."

Members of The Satanic Temple, an activist group that views Satan not as a deity but as an icon of rebellion, are criticizing Springtown ISD for allowing corporal punishment. The district made headlines in 2012 when a male assistant principal at Springtown High School paddled two female students.

The billboard displays the group's logo, which features a pentagram framing a goat skull. It also highlights a website that invites students to fill out a form that would affirm "the inviolability of the human body" as one of their deeply held religious beliefs.

If a student registers on the site and later faces corporal punishment at school, The Satanic Temple will send a letter to the school board on the student's behalf and even go to court to fight for the student's right to free exercise of religion, said the group's spokesman, Lucien Greaves.

Registering for the website won't make the students members of The Satanic Temple, Greaves said, but it will align them with the group's tenet that a person's body is inviolable and subject only to his or her will.

"This all comes down to us offering an exemption to corporal punishment," Greaves said. "We're hoping to get children to sign up to exempt themselves from corporal punishment policies, whether their parents agree or not."

The 2012 paddling of the girls in Springtown violated a district policy requiring corporal punishment to be carried out by school staff of the same sex. But after the incident, Springtown ISD changed its rules so that students could be punished by school staff of the opposite sex as long as a school employee of the same sex as the student was present.

The mothers of the girls who were paddled complained that their daughters had bruises.

"I gave consent for my daughter to get a swat, but I didn't give consent for him to bruise my daughter," Cathi Watt said, according to the Fort Worth Star-Telegram. "I don't think a female will raise a bruise because she doesn't have the strength of a male. I think this sends a message to boys that it's OK to hit a girl and it's OK to bruise a girl. That's not right."

The Satanic Temple said on its Protect Children Project website that it chose Springtown as the site for its first billboard because "they routinely hit students," but it offered no other examples besides the 2012 case.

No one answered the phone at Springtown ISD on Thursday.

About 2,700 people live in Springtown, which is about 27 miles northwest of Fort Worth.

Texas is one of 15 states that explicitly allow corporal punishment in schools, said former Education Secretary John King in a 2016 letter . More than 28,500 children in Texas received corporal punishment at school in the 2011-12 academic year, according to the most recent data available through the Department of Education.

However, many school districts forbid the practice, including Dallas ISD.

Headquartered in Massachusetts, The Satanic Temple eschews the supernatural and doesn't actually worship the devil, according to its website. Instead, it presents Satan as a symbol of defiance to authority.

The group considers beating children at school to be child abuse.

"We're not doing this to recruit," Greaves said of the campaign in Springtown. "We're doing this to protect children because we think it's a savage and backward practice."

The Satanic Temple has made it a mission to push for the separation of church and state. In 2012, it sought to install an 8½-foot-tall bronze statue of Satan at the Oklahoma Capitol to stand in contrast to a Ten Commandments monument. Oklahoma's Supreme Court later banned all religious displays on Capitol grounds.

The group ended up installing the statue of goat-headed Baphomet in Detroit, home to one of its chapters. Hundreds gathered for the 2015 unveiling that Time magazine described as "a cross between an underground rave and a meticulously planned Halloween party."

The Satanic Temple also took its controversial methods to the Michigan Capitol, where it has planted a "snaketivity" display since 2014 to rival a Nativity scene placed on the lawn during the holidays.

What is a "snaketivity"? It's a display that combines a snake, a cross, a glowing pentagram and a book with the message "The greatest gift is knowledge."

Last year, someone adorned the snake with a Santa hat that said "naughty."
