Three groups on Monday announced a coalition to win broader rights for LGBT Ohioans. But the coalition remains uncommitted to an effort to repeal the state's 2004 voter-approved constitutional amendment limiting marriage to heterosexual unions.

Equality Ohio, the state's largest gay rights advocate, announced the coalition in an email to supporters.

“Today, Equality Ohio, the Human Rights Campaign and the National Gay and Lesbian Task Force announce a powerful statewide coalition to win full equality in Ohio,” Equality Ohio Executive Director Elyzabeth Joy Holford wrote in the email.

“By bringing together our resources and expertise, we will join with our state and national allies to launch an unprecedented effort to achieve equality in Ohio,” Equality Ohio said in a statement. “Building on what we learned from last year's campaigns in Maine, Maryland, Minnesota and Washington, we will activate our combined memberships of over 75,000 Ohioans to fight for passage of the Equal Housing and Employment Act, statewide anti-bullying legislation and, ultimately, marriage equality.”

However, the coalition cautioned against acting too soon on the marriage front.

“We understand that there will be and are other efforts to do similar work in Ohio, including repealing Ohio's constitutional amendment banning marriage equality. While we believe that many hands make light work, we also know that acting prematurely or without the expertise of other like-minded groups can create dramatic set-backs.”

FreedomOhio began its effort to repeal the ban last year, and has said it will have sufficient signatures to put the issue on November's ballot.
