Heartrending. Yes, it's a bad situation for these kids, and we should try to get some help for them.
You have also managed to caricature the conservative perspective on the issue. I assure you that while orthodox (non-nutty) conservative are generally not in favor of welfare or more en lement programs, this does not extend to helping poor and abused children. I would imagine that conservatives would generally favor some sort of federal (or state) funding for such emergency programs.
Also, the church has a vital role to play in charity. While we can safely say that, in America at least, poverty for the adult is generally the result of poor decisions or the lack of education, this does not apply to the children. And it's not for the church to judge anyway -- the church's role is to dispense God's grace.
A good book on the issue: Keller, Timothy J., Ministries of Mercy. This is an object of discussion in the evangelical community.
