If that is what you think, then you dont know me very well.
That's just the way it seemed.
People have been baptized in rivers for millenia, it's common all throughout the West.
I, myself, was baptized in a river in North Idaho, and I have never, until your post, heard it referred to as "showmanship."
Discomfort with public expressions of Christianity was the ONLY explanation I could come up with for such an egregious misreading of Believers being baptized in a river...
