I don't like the New Atheists either, especially when their Atheism is just an excuse for pandering to racists, as in the case of Sam Harris.
But really, that "absence of evidence" thing does nothing for me. Absence of evidence for the Invisible Pink Unicorn doesn't make anybody want to contemplate her existence, right?
There are better ways to approach that.
Hey, for a couple million dollars, I'd be willing to change my mind and rebuke any scientist who refuses to be open-minded about her Invisible Pink Single-Hornedness. What's the name of that prize again, the one he received? Where can I apply?
