How is this any different then groups like the knights of Columbus or any other fraternal order of X. At least those groups came up with something original. "Let's copy something we constantly criticize, take what we don't like out of it, and call it our own" (yes I realize the irony)
I don't have any issue with them doing it. I just don't get why they would mimic something so many of them probably despise. Call it Hipster church or something.
