Massachusetts lawmakers are debating a bill that would ban therapies which attempt to alter a minor's sexual orientation from gay to straight.

The Legislature's joint committee on Children, Families and Persons with Disabilities held a public hearing on the bill last week.

The measure (H 154) is sponsored by Representative Carl Sciortino, an openly gay Democrat.

If the bill is approved, licensed professionals violating the ban could face revocation of their license to practice in the state.

“I actually know some adults that have gone through it and it's been a very painful, shameful experience,” Mark Blogier, a licensed clinical social worker, told 22News.

Social conservative group MassResistance told the outlet that it is opposed to the proposal.

“What they are doing is horrible, trying to keep families from seeking this kind of help, which has helped people, thousands of people, around the country,” said Brian Camenker, the group's founder and leader.

California last year approved a similar bill, though a judge, at the request of opponents, has blocked its start. New Jersey Governor Chris Christie has yet to decide whether he will sign a similar bill approved last month by lawmakers.
