(CNS News) -- Since South Dakota Gov. Kristi Noem (R) vetoed a bill to protect girls' sports from transgender "females" (biological males), 47 pro-family, conservative organizations have called on the governor to join their coalition to protect female athletes by supporting legislation that explicitly prohibits males from playing on female sports teams, in all grades and at the university level. 

"You recently announced your intent to form a 'coalition to defend Title IX' in conjunction with your surprising decision to use a 'style-and-form veto' on HB 1217, a bill that would ensure South Dakotan K12 and collegiate female athletes have a level playing field in their sports and that they have recourse against unfair policies that force them to compete against biological males," reads the letter to Gov. Noem, which was released today.

"We are already part of a large coalition defending female athletes across the country, and we are inviting you to join with us by supporting legislation that protects all women -- kindergarten to college -- and provides them with a legal remedy when their rights are violated, as HB 1217 does," states the letter.

HB 1217, the Fairness in Women's Sports Act, is the bill that Gov. Noem vetoed on Mar. 19, despite tweeting on Mar. 8 that she was "excited to sign this bill very soon." Noem reportedly vetoed the bill because of pressure from the South Dakota Chamber of Commerce, South Dakota Board of Regents, and multi-national corporations such as Amazon. 

HB 1217 would have required the public schools and colleges to designate sports teams as either male or female and based upon the player's biological sex. Every year, the players would have to provide documentation verifying their age, their biological sex, and affirm that they were not taking performance enhancing drugs. 

The legislation also would allow a player, team, school, college, or athletic association to take legal action if they experienced discrimination for not allowing transgender "females" to play on their women's teams. 

Currently, Idaho, Mississippi, and Arkansas have laws in place nearly identical to HB 1217.

"The South Dakota legislature got it right with HB 1217, and your original excitement to sign it was on the mark," reads the letter to Noem.  "They passed a strong bill that stands with your state’s female athletes, no matter their level of competition, and provides them a legal remedy when their rights are violated. We stand behind these legislators and South Dakota’s female athletes."

"Gutting the bill doesn’t help anyone win—it sends South Dakota and their girls and women back to the sidelines and sends the wrong signal to others across the country in the fight to save girls’ and women’s sports," states the letter.  "HB 1217 as passed protects all female athletes in South Dakota, not just those in high school or middle school."

"Your [vetoed and revised] version of the bill would hand South Dakota’s collegiate female athletes -- and a say in your state’s governance -- to the NCAA on a silver platter," said the pro-family groups.  "Why should collegiate females face injustice for achieving the honor of college-level competition?"

"[O]our coalition stands unapologetically behind these girls and women and won’t back down to pressure from the NCAA," reads the letter.  "The NCAA itself doesn’t require its member schools to allow biological males who identify as female on female teams. But even if it did have such a policy, we’d still rather stand proudly with female athletes than those who stand to profit off of them."

"So, we invite you, Governor Noem, to join our coalition on behalf of South Dakota’s—and the nation’s— female athletes who are counting on you to support legislation like HB 1217 as passed by the legislature," concludes the letter.
