Ever been to
Crosswalk.com ?
Go to the community tab, click on forums, and then on parenting. There is usually a thread debating that particular topic on a fairly regular basis. If you can't find a current thread, I know there is one in the archives. Some of the posters on that thread may consent to be interviewed. You will need to register (free) in order to post.
A hint - in order to avoid being TOS'd, don't post a question about doing interviews in the thread. PM the individuals involved, explain what you are doing, and ask if they'd be willing. This is a Christian forum that's heavily moderated (not that you have to be a Christian to participate, but they take the rules seriously) and if you are TOS'd on your first post, people aren't likely to talk to you.
