Recently someone said to me that there is no such thing as a slave respectfully disagreeing with her Master. He felt disagrement in a power exchange relationship is always disrespectful.
He felt a slave should defer to her Master. Thus there is no chance for a different opinion.

i felt really uncomfortable at this notion.

I'm not a slave and so this doesn't make much sense to me?
I saw myself as slave when I started but I soon realised i'm not.

I know there is no one way... but I wondered whether this was a prevalent mindset for those who see themselves as Masters.
