Intragroup Differences of the Non-religious: Attitudes Towards Same-Sex Marriage and Same-Sex Adoption in the United States

The Non-religious have been growing in numbers in the United States over the past decade. Yet even with their now large numbers we know little about the differences between various versions of non-religious affiliation. Using 2014 survey data from the Public Religion Research Institute this paper examines the attitudes toward same-sex marriage and same-sex adoption of the non-religious. Two non-religious groups are examined Non-theists (atheists and agnostics) and the Religiously Disengaged (non-religious but not atheist or agnostic). Our hypotheses ask if Non-theists are more likely to support same-sex marriage and same-sex adoption than the Religiously Disengaged. The hypotheses are tested across regression models that account for lingering religiosity, religious upbringing, and knowing a homosexual person. The data indicate that there are significant differences between Non-theists and the Religiously Disengaged across all models, with Non-theists being more likely to support same-sex marriage and same-sex adoption than the Religiously Disengaged.
