I'm not sure if I completely understand, so please correct me if I'm wrong. Are you saying that men are going to be intimidated by your intelligence and your advanced degrees? That they won't have your respect because of your degrees?
I don't think that's true. In my area, there are many, many women with advanced degrees and careers. Many who are actually the breadwinners in their household.
Now, if you're regularly talking down to people and implying that they aren't worth your time because they aren't as book smart as you, that's an entirely different story. (I'm not saying that's the case with you.)
If you limit your dating circle to men who have at least the same number (or more) of degrees as you, yes, you will limit your dating pool. But I don't believe that advanced degrees = bruising a man's ego.
