Excellent post and let's call it out how it really is. You hit the nail on the head with your "If you really loved me, you would" comment. It's not really intended as an insult, it's a manipulative ploy to trick the sub into doing something she does not want to - normally play.
I've got nothing against a degree of manipulation in the battle of the sexes, it can add a fun dimension to the mating game. And I suspect many females get a laugh at the ridiculous ruses doms come up with to snare them. But that's not really the case here. These doms don't try it on with the experienced subbies, they know they would get laughed at. They only try it on with newbies and the more inexperienced the newbie is, the more likely the doms will use this tactic. What bothers me is this is basically taking advantage of a persons ignorance and deliberately giving wrong information purely for ones own gain. It's like a taxi driver fleecing tourists by preying on his lack of local knowledge. And it's wrong, simple as that.
The "true submissive" insult is just one ploy in their bag of dirty tricks. Often they monitor new registrations sending mass mailing spam type introductions to snare newbies before they have a chance to get street wise. Send friends requests without ever having met the person. Claim to be experienced masters without providing any supporting details. Offer to provide training - and I think we all know what they mean by training. Lurk in chat without contributing, just waiting for a newbie to enter so they can whisper without permission in the safe knowledge that newbie is unlikely to complain. Then when the newbie does not do what they want they come up with the "true submissive" taunt. The gullible newbie who desperately wants to be acknowledged as a sub and be accepted in the community is supposed to fall to her knees saying "tell me what I must do to be a true submissive o great master". In my view this type of dom is not a dom, he is a charlatan, a carpetbagger selling snake oil.
The danger is newbies who don't fall for the ploy may become overly cautious and suspicious of every dom's intentions and the the site as a whole. Those who do fall for the ploy, when the dom has had his way and moved on to the next viction, are invariably left with a feeling of shame at having been so easily duped and leave never to return.
I applaud you Sir for bringing the spotlight onto this shameful type of behaviour but would have prefered you omit the offer to collar subs for their protection. The Mafia Godfather did provide excellent protection but it was rarely for the right reasons.
