The first openly gay bishop in the Episcopal Church is in Ellsworth Wednesday night as part of a campaign pushing for same-sex marriage in Maine. Bishop Gene Robinson of New Hampshire will be showing a documentary about his life called “Love Free or Die.”His visit is sponsored by Mainers United for Marriage, a coalition supporting a referendum on the November ballot allowing gay marriage.Robinson appeared in Portland and Lewiston earlier this week. Robinson was elected a bishop in 2003 and married his longtime partner in 2010 after New Hampshire voters approved same-sex marriage.When comes to Maine, Robinson believes support for it will grow here, too.”We’re really hoping that the movie will encourage people to talk to their family members, their friends, their co-workers and to do that little bit of education that will move them from being sort of a tolerant observer to being an active supporter and will go to the polls and vote for the freedom to marriage for all Mainers.””Love Free or Die” will be shown at 6:30 p.m. at The Grand Theater in Ellsworth. Doors open at 6 p.m. and the event is free. Bishop Robinson will be answering questions from the audience after the screening.
