Perhaps that is not the real question. The real question, from the perspective of enlightened social engineering in the progressive UK, is "should" fathers be passé? To which question the unequivocal politically-correct answer du jour is certainly "of course!"
Now that lesbians and single women only need some sperm in order to have their very own babies, raised without a demanding and oppressive male biological father around, and social science research is supposedly starting to confirm the unlikely proposition that such children are not just AS well off but in fact even BETTER off in some ways than children whose biological father lives in the home (apparently because two lesbians are more caring and loving than a mom and dad), well then - what else are men, and what else should they be, but prospective sperm donors?
This is the real victory of feminism. Perhaps one day we will be able to clone sperm out of women's cells - a story like that appeared quite seriously in the media last year. If that happens then we won't need men at all in the end, and we could essentially breed them out of the human race and into extinction. Hurray for peace in the world!
The funny thing is that even as Britain struggles under the clamoring of the reproductive rights lobby to take away the legal recognition of the importance of fatherhood, in America the government is trying hard to do the opposite: to make deadbeat dads take some responsibility for their children, to stick around rather than abandon women to be single moms, to make an appearence in the lives of their children. But why should they? According to the UK's reproductive lobby, the fathers have done their job - they donated the sperm and created the baby. The woman chose to keep it rather than having an abortion. And social science says that fathers are not needed after all.
So maybe we should all act like a pack of wild animals once again, and have the fathers disappear after the copulation is done, for everyone's benefit. That is, unless the woman wants to keep one around, not for the child but for herself. The rumor has it that men are good at certain domestic chores and other heavier work...but certainly nothing that women couldn't do themselves and just as well, or even better.
