I'm not sure those who regularly contribute to this site view themselves collectively as a sacred cow. I think they know they represent a certain mindset about architecture, set-up, conditions, and the "traditional vs. new" debate. Some tend to be quite evangelical about it, and some even suggest it's made a difference -- not the website, but the mindset -- in the development and recognition of well-regarded courses like the Bandon courses and Sand Hills.
As others have mentioned periodically on this website better than me, if you golf with anyone outside the orbit of GCA, discussions about archirtecture and set-up tend to be a moot point -- the everyday golfer just isn't obsessed about this stuff as the average GCAer. But I'm not sure that makes GCA anything of a sacred cow that's worth skewering.
