We cannot choose the categories of persons that we find sexually appealing, but we control our actions. Most people have sexual thoughts about others who are prohibited (e.g., the spouse of a neighbor, the cheerleader who lives next door), and even when the attraction is mutual, "we" control ourselves.
No one is condemned for "being homosexual," but we all have the right to condemn conduct that we believe to be grossly immoral, and to shun people who manifestly engage in it, while at the same time being respectful of their humanity.
Churches that embrace openly gay people are desperate for membership, and compromise themselves to get a few more butts in the seats. They relinquish their right to be considered a legitimate religion, at least in the Christian context. Again, homosexuality is not a sin, but homosexual acts are right up there with adultery. In Catholic lingo, "you excommunicate yourself."
