A very thoughtful post. I think something also to consider is that the population at large is more tolerant homosexuals. But the population at large is growing less tolerant of abortion. Look at surveys of young people on that subject and one will see a solid pro-life majority. Look at the bills in the various state legislature further restricting abortion. See the somewhat frightened quotes from Naral et. al. on the subject.
I think our elected representatives largely (!) cater to what the public wants. Right now, 30 years of propaganda is taking its toll and people don’t care about homosex. IMO, it will take another 30 years to reap those fruits and then the tide will turn.
Twenty five or so years of intense indoctrination in the government schools is all it took.
Soon your children will come home and tell you your car is too big, and you eat too much meat, then they will begin to remind you that old people have an obligation to die so as not to rob the young of their rightful inheritance.
We have a real problem with pro-homosexual indoctrination in our schools and our entertainment media. We're seeing the results, and seeing them the hard way.
You're probably right on increasing opposition to abortion on demand at all stages of pregnancy. Better lifesaving technology for extreme premature infants, along with the widespread use of ultrasound photography, is willing the battle to convince people that “it's not a choice, it's a child.”
Of course, without changes in the law, all that change in public attitude does is lead people to say abortion should be “safe, legal and rare” — i.e., discouraging people from choosing abortion rather than banning abortion outright. But at least it saves some babies.
