This is why people like Bob Sherwood don't bother to post here. He doesn't need to waste his time "arguing his case more extensively."
And where exactly is the charter of this forum which specifies that the purpose of it is to endlessly cross-examine proponents of DIR about the minutia of DIR? I know a lot of anti-DIR posters believe that's what its purpose should be, but most of the "proponents of DIR" have become tired of that game.
To be useful this forum should be about DIR and DIR divers. For the readers that aren't DIR, if this offends you, try to realize that not everything in life is about you.
And should I start posting in the solo forum trying to get the solo divers to argue their case more extensively? A DIR invasion of the solo forum could probably make that forum completely useless, just like this one...
I agree with what Lamont and others are saying. It is unfortunate, but it seems that opt-in is the only way to return this forum to any sort of usefulness. I don't have a problem with people asking questions, debating, poking around to see if DIR is for them, etc. But this forum has turned into a place where people who clearly have already decided that DIR is not for them to come and stir things up.
I think a new opt-in feature (like the solo forum) would help several ways. It might actually make people who are curious about DIR more likely to ask questions if they know they are not going to get blasted by anti-dir posters in this forum. Also, I really appreciate it when we get input from more experienced DIR divers, and instructors like MHK, Sherwood, and others. They might be more likely to post in an environment with less extraneous BS to wade through.
