Calm yourself! When you've done so, I'll walk you through this.
My point is quite simple, and obvious to the casual observer.
Otherwise attractive women whose main goal is to be traditional housewives have a rather easy time getting a husband. They're willing, and make it known that they're available and comport themselves with that goal in mind.
Professional women in general who wish the same must divide their efforts to a far greter extent while in college or building a career.
As all but the dullest preschool children can grasp, limited efforts and finite time lead to diminished results.
The question was not about whether professional women were less desirable, were less likely to end up in successful marriages if they did marry, or anything of the sort. The question was whether they had a harder time finding a husband at all.
To use a simple metaphor, a person who fishes daily will be more likely to catch a fish than a person who fishes occasionally.
There now! You see how we can arrive at reasonable conclusions when we eschew hysterics?
