I am assuming that you know that there is the worldwide "Anglican Communion" to which The Episcopal Church belongs...and then there are about 20 million Anglicans who belong to non-member church bodies.
In the USA and Canada, the Anglican Communion affiliates are among the most liberal in the world and are a scandal to African and Asian Anglicans (as well as to many conservative Anglicans in the West) because of the sexual issues that the UMC also is facing.
There are two kinds of Anglicans who have branched off from The Episcopal Church in recent years. First came the so-called Continuing Anglican churches which opposed theological changes in the liturgy and, also, the ordination of women priests. Homosexuality was not yet (1970s) an issue when they left, but these churches are opposed to same-sex unions, gay clergy, and all of that.
Second, and only since 2009, there is the Anglican Church in North America, which is moderately conservative overall, but left The Episcopal Church precisely because these people would not tolerate the gay agenda being accepted by The Episcopal Church.
