Heh... Many many children result from decisions made on ~very short~ time horizons.
This whole debate is a ridiculous red herring.
Oh really? A red herring is a fallacy in which an irrelevant topic is presented in order to divert attention from the original topic. So, if this is a red herring, then what is the original topic?
Very true. However, once the child is born do the majority of parents still make most of their decisions based on short term time frames? If you are taking care of a child the time frame has to be shifted forward. And if you love your child it has to be shifted very much to the future.
Based on your comment I will change my comment to "Only those who are caring for children or have cared for children should be allowed to vote"
