I have to question what sort of upbringing you had that you think the feminisation of men is a bad thing. Your post ranting at liberals probably gives me some indication but I guess I could try and reason things out anyway.
Showing your emotions is not a bad thing, because if you don't show your emotions then they have a tendency to get bottled up inside you and burst outwards, possibly in violence towards people, possibly in psychological trauma. There are many interesting ways that not allowing yourself to emote can damage you pyschologically, so I say it is a good thing that men are now allowed and expected in society to emote.
Secondly anyone who thinks women are somehow genetically predisposed to be more at home in the kitchen should perhaps return to 1912 where your ideas belong. I am a better cook than my sister, my mother is a better cook than my father, I can a better cook then some of my female friends, while I am a worse one than others of my female friends. If you were not to ascribe societally defined gender roles to children at all you would not mysteriously find that all of the girls had some sort of urge to cook things and potter around in a kitchen.
There is no such thing as a traditionally male role, unless you would like to go live in a cave and hunt wildebeest across the serengetti while your five sexual partners take care of your rapidly increasing brood. Anything 'traditional' is just an imposition of society.
Women are just as capable as men in almost every field they might endeavour at. The only exceptions that I can see being:
Fighter pilots. Women's bodies for some reason perform a little below men's at high Gs. It has been postulated that this is because of the different distribution of fat (mainly into the breasts, pressing on the chest) but even that is mostly supposition.
EDIT: Apparently my data may be out of date on this one, so take it with a pinch of salt. I'll remove it if anyone can provide me with some hard evidence for it.
Weight training: The strongest women are not quite as strong as the strongest men. This does not mean that all men are physically superior to women and should thus be in a position of power over them because there are probably several women out in the world who could kick your arse.
That's all I've got. Advanced Olympic-level weight training and fighter jets.
Your final point: Why do men necessarily need to be leaders of men and protectors of women? Most women seem to be able to protect themselves just fine and a female leader in most areas of industry is actually likely to be more competent than her male competitors, because in a male dominated field in order to get where she is she would need to be so much better than the men.
