It is rather dificult to read some statements made with text alone and corectly interpet them. As the human mind in normal everyday conversation (when in person) allows for the reading of body posture, facial expression and voice inflection we are not recieveing all the information.
Which makes it all to easy for us to assume someone is saying one thing when they are in fact saying another, or take offence at the wording of any given statement.
I would hope we all can keep that in mind, especially when "grilling" a new member. Anyone thats posted in the forums a lot knows we all have typed something others misunderstood and had our day on the duck pond being shot at.
Such examples of testing a submissives willingness to suspend disbelief are a common form of both play and training used by many dominants. Not only in the word of bdsm but also in the training of our own troops (at least according to my owner)for one example.
The main difference being that when in training, one isnt punished for suspending her disbelief but is instead rewarded for doing so. (unless the purpose of the training is being mixed in with the play) which is fine so long as the submissive knows this on an intelectual level, or it has been discussed beforehand. A dominant can indeed mess a submisive up if he isnt careful enough to make sure she isnt misunderstanding what is going on. Just becuase they didnt say that they are taking such care in thier post doesnt mean they dont.
Infantry forces for instance must be taught to "reverse" the teachings of both thier church (if they have one) and or common societal conseptions conserning physical violence towards the individual, so that when in actual combat they can "Kill" the enemy as opposed to freezing up.
Submissives sometimes must also learn to reverse thier own thinking in reguards to what is and is not acceptale. Society tells us our whole lives we are a slut or worse if we do or even think certian things. For some of us to really thrive in our submission (which the vast majority of society frowns upon) we too must be able to suspend disbelief, we sometimes must be able to take a word like slut and turn it around on itself.
There are many many paths to submission. Some steeper than others, just as some are more rewarding.
