I would be extremely annoyed for you or anyone else to suggest that a child of mine was a fashion accessory. The same goes for John, I'm sure. Are you saying he has no natural desire for a child? How do you know?
I'd go as far as to say that too many children are 'fashion items' as you call them - and that is regardless of the parent's sexual orientation. For one thing, more and more women are regarding having children as a right. It is certainly a natural desire, but by no means a right.
Anyway, are you extrapolating from the BBC interview or was that the main thrust of the discussion? I didn't see it so can't say.
I'm taking what was said and building on it, yes.
Statistics show overwhelmingly that children don't thrive in families where there is neglect and abuse. Nothing to do with gender imbalance. Children learn self esteem from healthy relationships where they see respect and they feel valued.
The two women in the interview were very clear in their reference to 'mothers' and 'fathers'. Furthermore, report after report from across the world has pinpointed the importance of a gender balance within parenting couples. Whether we take evolution or religious arguments, there must be a reason why humans have developed in the two gender patterns.
