Your sister-in-law recently announced that she is a lesbian, and she is divorcing your brother. Your sister-in-law would like to have custody of their two children, but your brother does not want his children raised by a lesbian

What can you tell your brother about the development of children whose parents are gay or lesbian that might make him feel better about the situation?
What will be an ideal response?

A good answer will be similar to the following:
More than a million children in the United States have a gay or lesbian parent. Most of the studies of these children have been done with children who were born in heterosexual marriages that ended when one parent revealed his or her homosexuality. In general, the development of children of gay or lesbian parents does not differ from the development of children of heterosexual parents. Preschool children of gay or lesbian parents identify with their own gender and develop typical gender-based activities, friends, etc. As adolescents and young adults, the vast majority of these children are heterosexual. On other dimensions, children of gay and lesbian parents do not differ in terms of intelligence, psychological adjustment, social skill, moral reasoning, or self-concept. Based on the research, your brother should be assured that his children are no more likely to develop problems with a lesbian mother than with a heterosexual mother.
