Some of that may be true
We’ve literally gone to 5 count them 5 different IFB churches and literally all 5 operate this way. Is it literally every IFB church in America? I don’t know there has never been a case study.
True story. Couple years back we went to visit friends that live in Indiana. We knew them in our IFB days. (This was after we left the IFB) they asked if we’d go to church with them and we said, absolutely. (This makes me laugh out loud every time) we go to Sunday school

and dontcha know it’s about dress standards
We love these people we really do. But my wife and I said, isn’t it funny they all say, yeah we know there are IFB churches like that but ours isn’t
I got another one

I’m serious true story. On my wife’s side we have a nephew that moved out of state and he invited us to visit. And of course the night before he said, we know there are IFB churches like that but not ours. This was a random Wednesday night. Yep, it was about always having questions
These were random services. Yeah yeah I know yours isn’t like this.
I have a few more examples if you need.
