I'm not sure whether it is or not; it depends on who is talking to whom. For individual Episcopalians and people dealing directly with them it is important - but for people dealing with Christians as a whole it comes under the heading of #NotAllChristians.
Just to start with - note that I am not Episcopalian.
That out of the way - Oh, gods, please no hashtags! And, I think this constitutes an abuse of the concept.
"Not all men," is a problem as a knee-jerk response to the report of a problem, as it constitutes a deflection from discussion the problem to mollifying the feelings of one person who feels they are being unjustly targeted, shifting focus from the problem to the rights of the accused. That's not happening here.
On the flip side, it is important that those who are the victims of discrimination do not engage in negative stereotyping, because then the moral high ground is lost. The response to, "Not all men!" isn't, "Yes, all men!" But is instead, "Yes all *women*" - a refocusing on the problem, not on insisting on accusing all members of a demographic or group.
Moreover, when considering what to do with the problem, it is *vitally* important to examine where things are improving - if you want to work to getting Christianity to change, the examples of where it is changing are your natural first places to start analyzing the phenomenon of change. This is why I said it was interesting. Why did the US Episcopalians move when the rest did not? What makes them different? If we want change, we ought to find out.
This is doubly true when (a) the point is that the Episcopalian Church is *no worse* than the majority of the country, only voting to allow what they could after it was already legal,
That's not the whole story - in 2012, they authorized a provisional rite of blessing for same-gender relationships, and discrimination against transgender persons in the ordination process was officially prohibited. So, it isn't exactly that they *only* moved when it was made legal. The Canadian branch had its commission meeting to revise their marriage canon to include same-sex marriage back in April 2014. And local Episcopalian Bishops have been supporting the move for some time - the Bishop of Chicago was a major proponent for his state to recognize same-sex marriage, for example.
Thus, we can see the organization has been moving (yes, more slowly than many want, but moving) in this direction for years. It looks rather much like the change in law was really just what allowed them to more quickly get where they were going anyway.
It is very common to characterize change in terms of "it isn't what I think there should be, so there is *nothing*", but that's not accurate. If we want to encourage motion, we need to know why some move, and others do not.
Indeed I could go so far as to say the ECUSA is the exception that proves the rule.
Yes, it does. In the original sense. You know how "Begging the question" doesn't originally mean, "Begs the question be asked". It means, "Assumes the answer of the question."
Well, "exception that proves the rule," doesn't originally mean, "exception that shows the rule to generally be true, by only being an exception." It means, "exception that *tests* the rule."
So, your rule is "Christian religions are homophobic." Fine. The US Episcopalians test that rule - they have been slowly moving towards inclusivity since the 1970s, even. When their precursors (Catholics and Anglicans) don't accept it, and other major organizations in the country don't accept it, why do they? They've been a bit ahead on other issues as well - ordination of female priests and bishops, for example.
One possibility is that, in contrast to the fairly strict "tradition and Papal authority" of the Catholic church, or the primacy of scripture of American Evangelical traditions, the US Episcopalians claim a triad of sources of authority - scripture, tradition,
and reason.
