Are Shifts in Same-Sex Marriage Attitudes Associated With Declines in Religious Behavior and Affiliation?

The anti-LGBTQ politics of the Religious Right has been implicated as one of the critical forces promoting the rise of disaffiliation from religion. The association seems plain given the rapid rise of the nones among younger cohorts of Americans – a group which also holds the most pro-LGBTQ attitudes. However, little work actually tests the link between shifting attitudes on same-sex marriage and declining religious behavior and affiliation. Drawing on the Portraits of American Life Panel study with waves in 2006 and 2012, we use appropriate measures to document the religious effects of changing views on same-sex marriage. We find that while shifting views did have a negative effect on church attendance and affiliation, these effects were not limited to shifts toward support for same-sex marriage and were not limited to liberals.
