I'm down with what you are saying as a whole.
Given the broad agreement, here's my local conundrum.
People don't use language in standard ways.
People here in the rural midwest are using SL or US-T phrasing to highlight the very idea you and I worry is getting lost---that these movements are somehow foreign.
It would take a lot of work to swap out the folk etymologies going on here.
I'd like to. But their folk etymologiy is being used to graple with new-to-them concepts.
