“…On the other hand, the various studies focusing on attitudes toward homosexuality (e.g., Hooghe & Meeusen, 2013;Kuntz, Davidov, Schwartz, & Schmidt, 2015;Kuyper et al, 2013;Takács & Szalma, 2013;van den Akker, van der Ploeg and Scheepers, 2013) or marriage and alternative forms of family formation (Treas, Lui, & Gubernskaya, 2014) have tended to address the general acceptance of "diverse family forms" or "diverse individuals" without addressing the issue of citizenship rights attached to this diversity. Exceptions to this include studies providing insights into attitudes toward the rights of same-sex couples in the United States (Doan, Loehr, & Miller, 2014;Miller & Chamberlain, 2013), Portugal (Costa et al, 2014), and Sweden and Norway (Jakobsson, Kotsadam, & Jakobsson, 2013). Yet few studies address attitudes toward parenthood rights or the issue of social rights for LGBT individuals or for alternative family forms, and almost none consider cross-national variation in these attitudes.…”
