Ed Whelan makes an interesting point:
Barack Obama may actually believe, as he stated yesterday, that Roe v. Wade "was rightly decided." But it may be very lucky for him, as the son born of that woman, that it hadn't been decided a dozen or so years earlier.
It's been noted in the past that legal abortion may in fact be reducing the ranks of people who believe in it.
I've been wondering what sort of evolutionary pressures are presented by available birth control of all sorts. It seems to me that the pressure that has given us our libidos that we all love so much has now transferred its support to a desire not for sex as such, but for children specifically. In other words, those who just like to get off are just getting off, and kids are being born to those who particularly want kids.
If this situation is allowed to operate the same way for a long time, I could imagine that in the future people will take only mild pleasure in sex, and will look back on our own appetites in that direction as bizarre. But they will feel a desire for progeny of their own so intense that we would consider it bizarre.
I suppose it's conceivable (so to speak) that our situation is favoring this trend so strongly that we're already seeing its beginning in the current younger generation. If so, the emergence of a population that wants children-of-our-own-genes might head off the "transhuman" future that many are expecting.
As long as leftists maintain posession of schools and universities, they have nothing to fear, no matter which way demographic trends go.
