Discriminate only means to distinguish or differentiate. By using terms like integrity and qualified they are discriminating.
The entire Bible is about discriminating between right and wrong behavior. The idea that we should not discriminate in this context is ludicrous. And desire is not enough to make an act moral. If it were then theft and deception would be moral behaviors.
These people seek to turn the gospel of Christ into a license for immorality (see Jude).
"I believe God does discriminate between good and evil."
Oh, I suppose He does, but not between good and evil people, at least not in this life. It is terribly wrong to say that God "punishes" except perhaps in a pedagogical way. The Fathers teach that at the Final Judgment we are "judged" not on our good deeds or bad, but rather on how much like God we have become. The Bible and Holy Tradition set out for us the proper way to theosis, to become like God. Certain practices are beneficial and tend to advance us in a process of dying to the self. Others, like sodomy and adultery, turn us away from God, focus us on our physical selves, blind the eye of the soul and cut us off from God. In such a state of isolation from God we embrace evil, scorn good and die. Not because God wants that, not because He punishes us, not because He is the author of evil for us but rather because we chose darkness over light, death over eternal life.
Herein lies the great evil of the ECUSA heresy. It is not Christian, it is purely pagan, pagan to a level probably not seen since about the 5th century. Man and his desires have become the measure of spirituality. The drive for "self realization" has replaced the desire for theosis. But is dangerously pagan (something the West is very prone to) to ascribe to God, Who is Ineffable, emotions or reactions more proper to a manmade Zeus or Jupiter.
This is not to say that ECUSA should be allowed to continue to infect the Anglican Christian Communion with its paganism, nor should it be allowed to hold itself out as a constituent member of the third largest Christian Communion on earth. The longer it remains, the more souls will be turned from God both here in North America and frankly around the world. But don't be tricked into making God in your image. That's what the pagans are doing.
