Episcopalians etc., are pagans and not Christian
Paganism is where we are the gods we worship i.e. we make up what god is like and the rules we want to follow. That may include polygamy, adultery, sodomy, pedophilia, pornography, murder, lying, stealing, slander, racism, slavery and corruption of every kind.
Christianity is following Christ's teachings that include a true obedience to the 10 Commandments as demonstrated in the "Sermon on the mount". Christians believe sodomy is a sin and those who covert need to repent of all their sins and mortify them in the flesh so that they may live by the Spirit and receive forgiveness for all their sins (Romans 8: 1-13).
