Nope. Just the people I know who are members. If that’s not doctrine, somebody is misleading a lot of people in that denomination. The people I know who are WSL refuse to attend any other church and refuse communion to non-WSL visitors. Their actions drown out any doctrinal words.
That The Wisconsin Synod doesn’t allow non-members to receive Communion hardly equates to a doctrine that non-members are all going to Hell.

Do you know "a lot of people in that denomination" from which to draw that conclusion? Or are you just extrapolating based on the handful you actually know?
