Baloney meter is going off. Too focused and intentional.
My bet? (90%) Bored teenagers. Likely attend (read: get dragged to) the church by a relative.
2nd guess (9%)= hoax. But hoaxers wouldn't have stolen anything. Or, would have stolen/broken anything that had value to homosexuals.
3rd guess (1% or less) = "hate" crime. But again, someone with real malice would have done more damage, or stolen\destroyed everything not nailed down.
But, by all means, the media should scream "HATE CRIME" at the top of their lungs, before all of the facts come in. Because homophobia.
