The Camp Meeting Association, in Ocean Grove, New Jersey, will have to start paying quite a bit more in taxes. The group own the beach and the boardwalk in the town (a town with a strong gay and lesbian presence), and that group is a branch of the Methodist Church. A New Jersey lesbian couple wanted to have their New Jersey civil union there on the boardwalk, which was designated "public" by the association in order to get a tax break to the tune of $500,000 a year. The Methodist Church said no, cited Bible chapter and verse, and the lesbian couple sued. Since it's public, the land has to abide by the state's anti-discrimination law.
From a press release from Garden State Equality (sorry, their website doesn't have their press releases, and I can't find this anywhere else):
The New Jersey Department of Environmental Protection today denied the Ocean Grove Camp Meeting Association's request under the state's Green Acres program for continued tax breaks for the public boardwalk pavilion area on which the Association has banned gay civil unions.
Well, you can discriminate if you're a religious organization, I suppose, but just don't expect a ginormous tax break if you do it.
But we could always do like Mexico does and ban churches from owning land and speaking on public policy.
