The Tennessee House on Monday approved a bill that would repeal Nashville's newly-approved gay protections ordinance.

The governing body of the City of Nashville and Davidson County, which merged in 1963, narrowly approved this month a plan to extend the city's gay protections to contractors, joining more than 100 communities across the nation.

The 2009 law bans employment discrimination based on sexual orientation and gender identity (transgender protections).

Republican Representative Glen Casada's measure would strip the state of all gay protections laws by outlawing municipalities from enacting anti-discrimination ordinances that go beyond state laws, which do not include gay protections. House members approved the bill with a 73-24 vote.

Casada told NBC affiliate WSMV that a different set of anti-discrimination laws on the state and local level could hurt commerce.

But in a video in support of Casada's bill produced by the Christian conservative Family Action Council of Tennessee a gruff-looking man is seen following a young girl into a playground restroom as a narrator asks, “Do gender differences matter to you?” (The video is embedded in the right panel of this page.)

“It's not any kind of statement that those who are transgender or cross dress are sexual predators,” the group's president, David Fowler, said in defending the ad. “It's that sexual predators will know how to take advantage of those opportunities afforded by law when the distinctions begin to get blurred with respect [to] who's righfully or not in a restroom.”

A companion Senate bill awaits a vote in committee.
