Looks like wishful thinking. The trend, as of now,
is not on the side of the conservatives, and that's in spite of the fact that the media portrays all Christians as a bunch of old white conservatives and tricks people into thinking they can only be religious conservatives or secular liberals (similar, in a way, to how they suppress third parties by not reporting on them).
I also find it quite rash to assume that a child will be a conservative Christian simply because their parents are. Heck, they could turn out to be militant atheists for all we know. And as long as folks like Pat Robertson remain the symbol of modern Christianity (you can blame both Christians and the media for that one), both liberals and conservatives will pay the price for it. You cannot simply "make the transition out of the faith more difficult" by segregating people. In fact, you risk alienating more people in doing so, hurting the religion even further.
As far as the culture wars go, even the most conservative of Christians are beginning to concede them. One of the biggest reparative therapy centers, Exodus International, closed its doors and the president apologized for the harm it caused not too long ago. The more the fundamentalists alienate themselves, and the more battles they concede, the brighter the future for religious progressives alike. All we have to do
is not make the same mistakes the religious right made.
