Chris, and for John U.K.'s information, there are several Lutheran groups, the one in the article, which might be the largest one in the U.S., Missouri Synod, which tilts either liberal or conservative depending on its leadership, and I believe the small Wisconsin Synod is quite conservative.
It is a shame that the ELCA fell into these heresies, they charities are noteworthy. They had an excellent conservative heritage also in theology, I think you'll find Professor Shodde's work, e.g., Interpretation as just about as good as anyone's of today. He belonged to the church that became the ELCA.
I would hope that this denomination would split between conservative and liberal churches so that at least,
1 Corinthians 5 6 Your boasting is not good. Do you not know that a little leaven leavens the whole lump of dough? 7 Clean out the old leaven, that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed.---NASB
