This study examined Chilean heterosexual women's discourses concerning lesbian and gay (LG) parenting following a social constructionist perspective. Data from a convenience sample of 15 first-year psychology female students attending an evening university program in Concepción, Chile, were collected through 3 focus groups. Findings through a thematic analysis indicated that the major concern participants reported was that children of same-gender couples would be discriminated, because of their parents’ sexual identity. A minority of participants expressed that having LG parents could disrupt a child's gender and sexual identity development. It is concluded that children in LG parented families are still regarded at best as potentially vulnerable to secondary prejudice and at worst at risk of gender and sexual identity disruption. It would be worthwhile training Chilean psychology students about the development of children of LG parents and also highlighting subtle and enacted forms of sexual stigma.
