As with anything, there are purists with everything. Capewind, if ya were to ask these guys for advice, then prepare your self since there is zero grey area with any of them, which is not very helpful unless you want to be involved into the hobby to that extent.
I am not worried about anyone being a purist, and I dont even find those type of views offensive. I've been involved in the dog world for more than 20 years, and have met all kinds. My personal opinion is most people are not "wrong" we are just all at different places on the "learning curve". Different experiences will lead to different views. What is important to me, is no matter where we all are on that learning curve, is we share our knowledge, and leave the person asking the questions in a place to form their own, informed, opinions
