I have to say, regarding the terms used in this thread, I have not seen the BWOD in quite some time, and the person who springs to my mind on this board as soon as I see poodle jacket is a vintage solo diver...hardly DIR.
I have seen and been a part of some pretty gnarley threads involving DIR, but for the most part these days these are those threads. It used to be an innocent question sparked a heated debate when someone posted their opinion and others didn't like it. Personally I thought opinions were what ran message boards...
Now the DIR ranting threads are started with exactly that purpose. To be honest it really seems that the pendulum has swung the other way, mostly people attacking what used to be fairly common DIR zealotry. The problem is those zealots have either left the conversation or matured, there is no need to keep the fight alive.
The problem is not so much tone as it is bias. If someone asks "what BCD?", sooner or later someone will suggest a BPW, and someone will invariably see something offensive in that comment, because they think it must be there. Hey, if you really want to be offended, you are going to find or invent reasons to be. As often as not someone outside that very narrow discussion will have trouble figuring out what all the fuss is for...
