This thread is so full of tired clichés that against my better judgement I am drawn back in.
If it is true that the defining feature of women is 'nurturing' then explain to me why it is that when in the first time in recorded history women have the rights and freedom to pursue alternatives they do so. Middle Class - the more affluent and educated women in the US and Western Europe delay childbirth and have fewer children than ever before. If the nurturing instinct is so powerful then why is this? (by the way I know you are going to blame it on patriarchal oppression just so you can insult even more those women that make this choice ).
If the defining characteristic of men is 'aggression' then why is it that most men abhor war? The warmongers amongst us make up some tiny percentage of of men - to the point of being an outlier group. Mature men at least, are kind, protective and seek a peaceable existence. That's more or less what 'being a man' - means - bear the pain, take it on the chin, be the bigger person.
The idea that our future is in parthenogenesis or the creation of artificial wombs in a lab somewhere is dreadful. We preserve the species through sexual reproduction and there are a whole spectrum of reasons why this is a good thing. Not least is that traditionally it required men and women to co-exist and look after each other (and the children) and stay in relationship even through the hard times. This is developmental for both men and women. Also sexual reproduction means the children are unique individuals and not clones of their mother (can you imagine being an actual clone of your mother! - I mean honestly!!! much as we love our mothers surely we don't want to be little carbon copies do we???) - and individuals mean variety and the potential to adapt to circumstances and thus survival.
I refuse to accept a future based on women hate men/men hate women - it is weak minded, crass and more importantly a dead end.
