Nah, I wouldn't say that. They just want to keep the cruising off-premises... which seems pretty reasonable to me.
They're actually located across the street from the headquarters of the Human Rights Campaign, and presumably have plenty of gay members. I'd be very surprised if this was motivated by homophobia (although I suppose that's not my call to make).
Fair enough, you're probably right. Remembering back now, I was pleasantly surprised when the Lifeguarding course I took at the Y was almost entirely absent of the sermonizing I had expected. Not as crazy religious as I thought.
