Shermer isn't just falling for a hoax. He is propagating the hoax by publishing it in his magazine.

I am more concerned about doubt without any particular method behind it. For example, the global warming deniers doubt global warming not because there is evidence that supports them but because it doesn't fit with their political position. The evolution doubters are not doubting for any reason other than it doesn't fit in with their religious theory.

I want people who are going to go about doubting things to do it a little more scientifically.
