In some ways our society fosters the belief that love is diminished, devalued. Just: people are told it doesn't matter so much. Many men refer to marriage as being 'pussy whipped'
The idea of wanting to be with someone - especially if they're not 'perfect' - is negated to the point of it being seen as a blight or a personal flaw if you believe in it.
Back to the more specific fact of the modern woman (I think labeling it a product of 'feminism' isn't quite spot on, there's more to it than that): Every woman in my life upholds the belief that if they're ****ed up, have issues (etc) their partner should love them anyway. But if the man is equally ****ed up or has issues (because they default to the idea that men can be physically stronger and are more prone to violence) they're less likely or willing to give that man the same consideration.
Men who struggle with emotional, psychological, and neurological disorders are treated more harshly by both men and women than *women* who have these same exact issues (regardless of how they choose to act out).
I don't think it's 'feminism' in a way - I think *some* of it is 'over the top feminism' and *some* of it is just plain old society having skewed values.
