I think the stuff that's taken their place is even worse. Same thing with female role models. The former have become self hating and weak, and the latter selfish and aggressive.
To put it in its simplest terms possible using your terms; because the old male role models were selfish and aggressive, the old female role models were self hating and weak. Thinking there's very much of use for modern society in those old ideals won't yeild much in the way of positive social advancement, they were restrictive, promoted knee-jerk judgemental values that attacked anything that wasn't completely generic in thought, behaviour and appearance. Third wave feminism at least has the advantage of allowing some modicum of diversity of behaviour and lifestyle and moved away from old fashioned 'behave exactly in THIS manner because it's best' ideas which characterised the period referred to in sociological circles as "solid modernity" (that being the period between roughly 1870-1980).
I wouldn't at all agree that the current mainstream social models of behaviour can be characterised as selfish and aggressive for women, self-hating and weak for men. There are plenty of aggressive fuckwits in both male and female sub-cultures, but the 'average' model of acceptable social behaviour does not encourage overt aggression or self-hating in any population.
(I can't do this without refering to alot of sociological key phrases, but I'll try to keep it to a minimum. Unfortunately the biggest thing about sociology is that most of the ideas are interconnected and impossible to express accurately without roughly a billion words.)
The good thing about third wave feminism is that it relies heavily on the principle of liquid modernity. Liquid modernity is probably best explained as being what we're all living in now. It's different to previous forms of our modern society where there were explicit rules and expectations with mass movements and beliefs (like the 50ies). That older form is Solid Modernity, of which second wave feminism is a great example (all men are this way, all women are this way, everyone should do this one thing because it's the best). Liquid modernity is more subjective and de-centralised than the older forms of modernity and as a result can be pretty hard to get your head around sometimes - there's no finite 'best' answers anymore, everything is dependant on everything else and there can be roughly 30 quadrillion different viewpoints all co-existing together under the umbrella of 'liquid modernity' without anyone knowing what's what and everyone having different ideas based on whatever subjective interpretation of whatever source they happen to pay attention to.
Essentially, third-wave feminism promotes chosing your own values and sources. You want to be a girly girl? Want to be a tough corporate woman? Want to be a motherly housewife? Want to be a butch lesbian? Under basic third-wave feminist principles, all those ideas are fine and dandy; girl power! Chose your own destiny!
I don't get the feeling it applies so much to males. We have a little spillover from general liquid modernity principles (y'know, do what you want, chose your own values etc.) but when it comes to social acceptability of behaviour, dress or other things, it really still seems that men are subject to more conservative, centralised societal values than women. To use it again; A woman wearing jeans or cargopants in public is fine. A man wearing a skirt in public would at the very least face strong social pressure to not do that again, and in certain regions could even face legal trouble as a result.
(edit: I'm just using this as a historical example. 120 years ago a woman would also face legal trouble if wearing pants in public in the exact same way. As a society we've managed to stop one from being taboo, but not the other).
The sex segregations that can happen in sports are more pronounced (still very segregated, I mean) however even there you can see a fair few double-standards. The social stigma for women choosing to play contact sports is arguably less than the stigma for males who refuse to play contact sports and would rather sit it out.
They're small differences, but if you have problems conforming or feel compelled to conform when you don't want to, they're cumulative differences and can start being big issues. "my choices are being a shallow fuckwit to fit in or being a pariah for not being a shallow fuckwit" starts being a problem when it's something you face every single day of your life.
Again, I'm not saying women don't face major social issues along the same vein. Third wave feminism provides only a small buffer against stupid fuckwits and social isolation. I'm just trying to illustrate that there actually is a reason to think that gender inequality is a two-way thing and needs to be looked at critically. It's just that there's already plenty of skilled and intelligent advocates for women's rights and getting rid of outdated female values... but finding constructive and inclusive arguments for overturning outdated male values is fairly rare.
