In reply to Jais H. Tinglund.

Jais,
Not sure if you'll see this since it is so much later, but I was wondering the same thing. Who among the Thrivent members is pushing this neutrality? The fact that the ELCA several years ago voted to approve abortion as a moral option for their members must indeed mean that there are lots of Lutherans who probably do not want Thrivent to take a pro-life stance, unfortunately. And it may well be that the current board of Thrivent is made of a majority of those who at least somewhat endorse abortion, unfortunately. But that said, the fact that so little of the charitable funding was directed to abortion-providing facilities like Planned Parenthood and so much to pro-life organizations seems to indicate that those who care about this issue strongly are pro-life and adamantly opposed to abortion.
So your question seems valid: Who would have adamantly objected if they just ruled out abortion providers and kept the pro-life groups?
Even in our secular government, which adopted the Hyde Amendment to assure that no tax dollars went to fund abortions, as far as I know they didn't feel obliged to equally censure all funding that might be used to provide help to mothers so they could carry their baby to term, give birth and either adopt out or have support in caring for the baby.
