This document summarizes research supporting prohibiting adoption, foster parenting, or child custody by households including homosexual members. It claims that:
1) Homosexual relationships are less stable than heterosexual marriages, contributing to higher household transitions that could harm children. Research also shows higher rates of mental illness and relationship problems in homosexual individuals.
2) Households with homosexual members uniquely endanger children by exposing them to higher stress levels from issues like mental illness, relationship instability, and abuse risk. This could psychologically harm children.
3) Children may learn that homosexual behavior is normal through exposure in the household, but research indicates that it may actually increase their risk of engaging in homosexual behavior themselves.
