The ELCA may now permit open communion, but the Missouri Synod does not. We believe that our Savior is truly physically present in and with the bread and wine. Most Protestant churches do not share this belief (I don't know what the ELCA believes, as I left that church 30 years or so ago. I wanted to join the Roman Catholic Church, while Mrs. Lucky, then a Methodist forced a compromise).
No, I don't share that belief.
I do object to the sort of open communion I witnessed in one Lutheran church. My belief is that communion is open to believers. I saw children of an age who could not possibly have made a choice for Christ taking communion with their parents. That is too free for me.
Yeah, I can see why religious discussions between various denominations could get a bit psychotic.
