A group of conservatives led by Delegate Neil C. Parrott, a Republican opposed to gay rights, have launched an effort to repeal Maryland's recently approved transgender protections bill.

Democratic Governor Martin O'Malley has pledged to sign the Fairness for All Marylanders Act of 2014 (SB 212), which seeks to prohibit discrimination in the areas of employment, housing, credit and public accommodations on the basis of gender identity or expression.

The group began collecting signatures for a ballot initiative at MDPetitions.com, The Washington Post reported.

At a press conference Tuesday to announce the effort, Parrott said the group he chairs worries that the legislation will allow men claiming to be women access to women's restrooms. The group has dubbed the legislation the “Bathroom Bill” and its repeal campaign includes imagery of a stick-figure man climbing over a bathroom stall to reach a stick-figure woman.

“It opens it up to predators, not necessarily transsexuals, but predators who will take advantage and go into the opposite-sex bathroom,” Parrott told reporters.

“The unintended consequences of this law demand that we take it to a petition,” said Delegate Kathy Szeliga, also a Republican.

The petition claims that the legislation “will require businesses to open up their public facilities … so that men can use the ladies' room and women can use the men's room.” However, an amendment to the bill added to counter such claims defines gender identity as being “sincerely held as part of the person's core identity.”
