The fault, imo, is that LW faults all of us first for not agreeing with his opinion. Your logic is fallacious because the order of posting lends no priority to who is opining and who is claiming fault. LW gives us a "hard and fast" set of definitions and defends them as correct. That means he espouses them as truth, not opionion, and that means Dawg's statement of fault is in fact, correct. Now I personally don't agree with much that Dawg espouses, but there is rarely an arguement because he is clearly professing his opinions and not proposing a set of truths to be universally adopted.
My very first arguments with Sir Russell and others, (mostly resolved now) all revolve around their offering up such definitions and professing them as absolute and irrefutable... all of which left me "outside" of the lifestyle.
First come the titles and labels, next come your kinks. What will happen if someone says your particular kink (whatever it might be) is out of bounds, too dangerous, or not to be "permitted" by good kinksters everywhere... because invariably, that comes next.
