I wouldn't say all managerialism inside evangelicalism is structured. Perhaps some, like the situation in the SBC for example.

However the influences behind the managerialism within evangelicalism does make for attempts at gatekeeping and marginalization, even if largely originating from various sub-tribes within evangelicalism. They are almost always the same motives, and aimed at the same target(s).

I am encouraged to see you admit that such efforts at gatekeeping are futile.

I agree.
