Only a few days ago, Rush was using sound clips of an appearance by a Republican on Hardball who was being grilled by Chris Matthews on the subject of evolution to explain what his response would be in the same situation. To summarize, he said that there is no doubt that evolution exists. That evidence is clear. What cannot be explained is creation. Evolution doesn’t explain it. The big bang doesn’t explain it. Science can explain how it all unfolds, but not how it all began.
From listening to Rush over many years, I would say that his problem with the presentation of a discovery like this is that many in the scientific community would like to use it as a vehicle to subtly (or not so subtly) attack religious faith. “You see, the whole thing can be explained in scientific terms. Religious faith is just a silly relic of the past.”
Rush may have been inarticulate at this particular moment, and if you just dropped in, you might not realize it. A shame to dismiss him as an ignoramus based on that.
