Kevin, just as some of the previous comments said, sure boys play with dolls. They are called "action figures." Whether GI Joe or Captain America boys use "dolls" to develop their imaginations. As for "dolls," none of my 9 sons wanted anything to do with them unless they were playing with their sisters and the dolls had to be " rescued" from the bad guys.
As for your overall question, for the past 40 years there has been a systematic attack on the nature of men, the role of men, the importance of men, and the relationship of men in both the family and society. Along with the attack on the Church, the Left has attempted to, and in some ways succeeded, in allowing men to succumb to the more base tendencies. We men have much work to do.
