blood shortage and conservatives

I read recently that conservatives are having more children than liberals. We can see the results in the continually low supplies of blood. From my experience of company blood drives, conservatives rarely give blood. I am 5 feet tall, weigh just enough to give blood (a little over 110 lb), have a low threshhold of pain, and have given blood at least 8 times, and plan to give more. When I have been able to persuade/shame tall, healthy conservaties to give blood, the poor things are absolutely traumatized afterwards. But these wimps are eager to send other people to war and inflict torture on others.
