There was an excellent interview in Danish radio with male/couples therapist, his take was really interesting. There are three groups of men, in his view. The lower class, being uneducated and poor, the upper class, being extremely successful. Both of these group have no problem with the changing male roles or feminism, they just ignore it or it doesn't affect them. They just continue as always and it works for them. Then there is the largest group of men, the middle class. They're told that the male role has to change, or is changing, and they do as they always do, they adapt. The kicker in this thesis is that they're then told that everything is still wrong. That is confusing, angering and leave a large number of men in a state where they no longer care or they develop an anger towards modern society and women.
The solution, again according to this theory, is not to redefine the male role in society, because that was never going to work. Instead we should return to the traditional male ideals, without the negative aspects. In essence to bring back the gentlemen.
Personally I like this theory, because it has practicality, something that is lacking in the idea that men need to evolve, adapt or "find their place in modern society".
