There are many unwritten rules and protocols in the world. For example there is no rule to not walk up to a married person but everyone knows it’s not right to do so. What about things like girl and bro code and so many others. Yet some dumbass Dominant in our world and lifestyle that can be so highly sensitive, rigid and regimented, decides to disrespect another by approaching their submissives without permission. That just shows what kind of person and Dominant that person is.
If the OP feels disrespected? That is disrespectful and any sane person should know not to do this.
Now if there’s real and legitimate concern that some form of abuse is going on, then that’s totally different. If not, the Dominant is asking for whatever she/he gets.
