The city’s Human Relations Commission on Thursday will participate in a forum on gender identity issues.

The forum, which is open to the public, will feature a showing of the documentary, “Call Me Malcom,” which chronicles a female seminary student’s transition to a male. A group discussion will follow.

The city’s Human Relations Commission is participating in the forum as part of its deliberations on a proposal that would make the Lawrence the first city in the state to legally protect transgendered people from discrimination in housing and employment matters.

The forum will begin at 7 p.m. at Plymouth Congregational Church, 925 Vt.
