What is the meaning of this? The Essence of Disrespect? World renowned couples researcher John Goffman calls it contempt. I call it the foundation of disrespect and utter disdain for another person.
I am tempted to say, “how dare you!” be so high and mighty, arrogant and omnipotent. It is a power play with some control added for flavor. I am feeling powerless now so when I can jump on you and make you appear to be inferior I will feel a bit better myself after I take you down a few pegs. This is an attack ladies and gentlemen. No doubt about it! Disrespect is a lack of courtesy. A public display of grammar correction is a stealth move played often when no one is paying attention. It is a one up move from some one who feels so shitty about themselves and their lot in life they can’t help but take shots at others. It borders on a control addiction but not quite. A correction is more about help me I am drowning no one will talk to me so I have to get attention some how. Aha! With my smart and attentive brain I will tell you how stupid you are and I can listen to how smart I am. It is really nice to hear my own voice that is really what I wanted all along. I had to take you as hostage just so I could get what I wanted.
Your grammar correction counter measures for now.
A simple question, “What needs are you trying to get met by saying that?”
