Dogma fouls up a lot of things. While guidelines and conforming ideas are helpful in creating a distinctive culture, when they get to be oppressive and limiting, they often strangle innovation and growth. I think our hobby is pretty self-limiting and strangled as it is.
One of my "aha moments" in starting back in to audio as a hobby was to see an "argument" occurring in a forum post somewhere. One fellow was actively dumping and criticizing the systems of others who had posted pictures of their equipment and viewing setups. He was getting personal and nasty. Then he was challenged to put up a photo of his viewing room and equipment. He did. His equipment was all big box stuff on a cheap set of shelves in a dump of a room.. I remember being shocked that someone with such "ordinary" equipment in a dump of a room would have the temerity to actively criticize and bag on other peoples choices.
I made it a point to never criticize or dump on the choices of others. I have no idea what kind of baggage they carry in their day to day lives. Who am I do dictate choices? Who am I to "know better" what to choose?
