The Maine House of Representatives on Wednesday overwhelmingly approved a bill that seeks to prohibit therapies that attempt to alter the sexual orientation and gender identity of lesbian, gay, bisexual or transgender youth.

Such therapies go by names such as “conversion therapy,” “reparative therapy,” “sexual orientation change efforts” or “ex-gay therapy.”

According to the Press Herald, Wednesday's vote was 91-46, with five Republicans and five independents joining 81 Democrats to approve the bill. The bill now heads to the Senate, which is controlled by Democrats.

The bill was introduced by Representative Ryan Fecteau, an openly gay Democrat from Biddeford, and Senator Linda Sanborn, a Democrat from Gorham.

The Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, called on the Senate to quickly take up and approve the bill.

“It is heartening to see the Maine House of Representatives stand up for LGBTQ youth by passing this critical legislation that will protect some of the most vulnerable Mainers from an extremely damaging practice,” Xavier Persad, senior legislative counsel at the Human Rights Campaign, said in a statement. “So-called ‘conversion therapy’ is a harmful, debunked practice that has no place in Maine or anywhere else. We’re grateful to Equality Maine and Rep. Ryan Fecteau for their leadership in ensuring this bill passed through the House with strong bipartisan support. Now, the Senate should act quickly to pass this legislation and send it to the governor’s desk.”

Lawmakers approved a similar bill last year, only to have it vetoed by former Governor Paul LePage, a Republican who said that he had “grave” concerns that the measure could be interpreted “as a threat to an individual's religious liberty.”

An effort to override LePage's veto failed.

Governor Janet Mills, a Democrat, has signaled her support for the legislation.

Fifteen states plus the District of Columbia have similar laws. Colorado lawmakers recently approved a similar bill and Governor Jared Polis is expected to sign it into law.
