I agree. There's nothing wrong with voting according to religious principles. What's wrong is creating public policies endorsing particular religions and so on.
It definitely makes a difference in attracting young people. Some claim the main line churches are losing members because of politics but I don't believe that's true. Because of our worship style, absolutely.
I'm sorry there's a struggle. I like more traditional services but as long as you aren't making up your doctrine I don't see why the two service system is not good enough.
I don't believe in "speaking in tongues," but, to each their own.
