Due to how the data are collected, the Episcopalians are generally lumped with "Mainline Protestant" on the big comparisons and broken out separately only on sub documents that focus on Protestants. But I pulled the Episcopal data and added them to the Big Table for your interest. I named these a little differently from the Pew data: "Unaffiliated" means people of faith without traditional affiliation; "None" means no religion/atheist/agnostic, etc.
The first graph looks at levels of education, from no school, to high school, some college, college degree, or post-graduate work. The chart is sorted in descending order from those with most education (College + postgrad combined) to those with least. As you can see, the highest levels of education are non-Christian faiths (Hindu and Jewish), but the 'piskies are pretty high. More conservative Christian denominations such as the Roman Catholics or Evangelicals are much further down the chart, indicating that a larger fraction of those belonging to this group have lower levels of education.
The second chart takes the same groups and asks whether they have a positive or negative view of gay people. Although there is some expected agreement, this chart does not completely correlate with the education chart; for example, Hindus are much less favorable to gay people, although very highly educated. The unaffiliated group is most gay-positive, and the Roman Catholics are right up there with the Episcopalians. Perhaps someone should tell the RC Bishops, who are busy attacking gay marriage around the country, that they've lost the people
Still, a recent study from Florida notes that more educated people are more favorable to gay rights.
The study found education was about five times as important as race in determining whether a county's residents favored the ban. .....I don't think any of us are surprised with that. But it is interesting how different the denominations are, don't you think?
"There's a lot of evidence showing increased education leads to greater tolerance," Smith said.
