There has been a lot of discussion in news media about religious opposition to gay rights. To test these claims, I set out to compare religiosity (as defined by how frequently a given respondent attends religious services) with support for gay rights (in this case, defined as support for gay marriage or civil unions). I also sought to compare the effects of religious denomination on support for gay marriage. In comparing all these variables, I found that religiosity does have a strong impact on support for gay marriage. However, I found that religious denomination (with the exception of moderate Protestants and unaffiliated persons) had a statistically insignificant impact on support for gay marriage.
