" I object to the promotion of homosexual practice"
A few days a good I heard a local pastor proclaim that true Christians find both the National Council of Churchs and the World Council of Churchs repugnant, because both "promote" homosexuality.

I just checked the dictionary. The definition of "promote" that appears germaine here is: "the act of furthering the growth or development of something"

How many more people do you think will decide to become homosexual if same sex marriage is legalized? How many people homosexual people will begin to practice sex for the first time because same sex marriage is legalized? What will grow, or be furthered, because same sex marriage is legalized. ?
