Really? I didn't know there were many conservative Episcopalians left
Not many, but some. Usually they don't dominate an entire diocese (I think the only other diocese that are like this, is maybe one in upstate New York and maybe one out west).
Alot of it is due to regional culture and episcopal polity. Orlando was the scene of alot of charismatic revival among Episcopalians back in the 70's. It also has alot more retirees than other parts of Florida and the nation, and they tend to be socially conservative. The bishop basically carved out a mini-feifdom, even though the rest of the state is more or less the same as the General Synod. And there's the strong presence of the Reformed Theological Seminary in nearby Oviedo, where most of the clergy go for theological training. The Reformed Theological Seminary trains alot of clergy that go to evangelical, but not mainline, denominations. The diocese also has connections with GAFCON and Sydney Anglicans, both are reactionary or fundamentalist forms of Anglicanism, schismatic or sectarian by nature (and sometimes anti-Catholic), and sternly Calvinistic and patriarchal (alot of parishes here do not ordain women, or restrict them to deacons).
Currently, the Diocese of Central Florida would be in violation of the canons of the General Convention, which requires bishops to allow priests to marry same-sex couples, but so far only one parish, St. Richard's of Winter Park, which already has alternative episcopal oversight, actually is open and affirming. The rest either have congregations that are opposed or divided over the issue, and aren't seeking to marry gay couples or call openly gay people to be rectors of their parishes.
I used to be more involved in the Episcopal Church down here as a regular churchgoer. I wasn't a member, though . In the end I decided to move on due to the fact I didn't find the influence of Sydney Anglicanism and the Reformed Theological Seminary to be my liking, to say nothing of the attitude some have about gay people.
(And NO! I do not mean that as insult. It's been my experience Episcopalians tend to learn towards the left, socially).
The clergy tend to be so more than the laity, who tend to be more evenly divided. Keep in mind several conservative justices, politicians, and media personalities are Episcopalians (Neil Gorsuch, Tucker Carlson, Eric Metaxas). Historically, Episcopalians were called "the Republican party at prayer", in fact... but that was before the political shift of the early 2000's, when highly educated professionals and academics started voting Democrat almost exclusively, and changed the political demographics of the episcopal church. Mind you, peoples actual politics didn't change, so much as the Republican party changed underneath them.
