The homosexual is equal in God's eyes to the heterosexual.
Parents must love their children, including the child who is homosexual. At the same time, a homosexual child must understand a loving parent's sadness over his or her inability to sexually love a person of the opposite sex.
Society has the right and obligation to prefer heterosexuality to homosexuality. It is better for children -- they need a mother and a father. And it is better for the individual -- a woman makes a man a better person; and a man does the same for a woman. Advocating heterosexuality as society's ideal no more implies bigotry or "homophobia" than advocating marriage implies bigotry against singles or "single-phobia."
Societies that regard homosexual sex as the equivalent of heterosexual sex have far more homosexual sex. Ancient Greece esteemed man-boy sex, and consequently had far more of it than modern society.
Men who are not sexually attracted to women have no choice about being homosexual. Proponents of heterosexuality should, therefore, use the word "choose" sparingly when referring to homosexual men.
We do not know why people are homosexual. The cause may be genetic, or it may be neonatal, but we have nothing approaching proof for either explanation. It may also be psychologically induced, and in some cases this can be shown (e.g., gay men who were subjected to sexual contact with a male when they were boys). In none of these cases can a homosexual be said to have chosen to be one.
Many women in lesbian relationships, however, can find some men sexually desirable. Such homosexuals can be said to exercise some degree of choice.
A significant percentage of women in lesbian relationships have come to those relationships primarily as a result of sexual abuse by a man.
Bisexuals, by definition, exercise choice. They can be asked (though not legally coerced) to limit their sexual behavior to heterosexual relationships.
It is unfair to a child who can be adopted by a married couple to be adopted by a same-sex couple. Children have a basic human right to a mother and a father.
The Boy Scouts have the right and the duty not to place gay men in situations where they are alone with boys -- just as the Girl Scouts should not place heterosexual men in positions where they are alone with girls. Yes, most gay men control themselves around boys; but the disproportionate sexual abuse of boys by homosexual priests suggests that some proportion of gays will not be able to control this desire.
