Kind of what I said - I don't know that any of these people have the real estate in mind when they challenge teachings on homosexuality or whatever, but Satan I am SURE does, so he uses them as his pawns to corrupt the most visible witnesses for God in society.
I send my kids to an LCMS school. If I didn't already belong to the local E. Covenant church I would go to an LCMS church. There are some unscriptural teachings in the Covenant church, e.g. women pastors, creeping in to the higher levels that are disturbing, but so far our local congregation is aware and opposed to them. I had to laugh at some of the articles that come in the denomination Magazine - about gun control (pro gun control) and lamenting the fact that 'women pastors' in the Covenant denomination are finding it hard to get called to a church! Boo hoo.
