The thing about abortion is that it's one thing on which it's impossible to be purely rational and calculative. Call me soft but the idea of snuffing out a helpless life in the womb just...doesn't strike me as something conscionable. Plus, you have consider how many white children are also being snuffed out.

The US has already become a non-white country and whatever percentages you think you are saving abortion is vastly overwritten by massive immigration from Latin America and China. Whites should think on a global scale like Jews. Being a global minority, they should think about preserving absolute numbers.

My guess is that there would be at least 20-30 million more whites in the US today if abortion had never been legalized. Sure there would be 20 million more blacks but you'll get 20 million blacks more regardless as they open the gates to Africa. So in the end, the only difference is that you lose 20-30 million whites in the long run.
