There are nearly 1.5 MILLION abortions performed in the US each year, I would seriously question if even 1% of those are a result of rape or incest. However, I agree with the premise that the pro-death crowd uses rape and incest as a "red herring" to avoid the real issue and that is that we have lost nearly 50 million people in the past 33 years. When you consider that statistically about half of them would have been female and many of them would now have children of their own, the loss is staggering.
At least we've got the illegals to fill the void...
