dredz_boi: I don't believe in roles either, because, well, it just goes back to old traditions as the man having supreme dominance over women --just slacking up ever-so-often each generation until we are at the point we've reached, exceeded and still struggle to press beyond (woman's rights, unfair pay/ gender bias). Just an observation I've made since my existence.
Back then, a man wouldn't dare have a wife making more than him because it made him seem weak and incapable as the ruling head, so, while he's off making those ends meet, the wife made sure all the house hold duties were managed. Now that women have careers and are power players, personally, I see no reason for said roles. They've proven they are equal. I can clean the toilet and prepare dinner just like she can mow the lawn and take out the trash.
I agree about equality as human beings. However, you do remind me of one basic difference between man and women, and that is in general, physical strength.
Actually, there is a second, and that is, again, not making a blanket statement here, but generally, men tend to be more mechanically minded, though I am not averse to assembly the odd IKEA product!
