Dr. Scott Stanley: I think it has to do with a resistance to "moving across the line." When males cross the line, there is a huge step up in their sense of identity about the commitment and their level of responsibility. So essentially, there's a resistance to crossing the line. Because right now, men can get so much of what they want without crossing it, and they only see increased responsibility from crossing it — "why would I be in a rush to do that?" In the meantime, they are often treating women in a way that diminishes their value even while they hang on to all their power and choice.
