The "theory" that George W. Bush was born from Barbara Bush is a belief system no different from the theory that he was born from a humpbacked whale.
Well, there's a little bit of difference: one is TRUE and the other is FALSE, and one is supported by FACTS and other science, the other is NOT. Aside from that TINY difference, both are equally valid theories </sarcasm>
Is it GenX that thinks that every opinion is just as valid as another?
