But where's the evidence that it actually happens?
I know that the claim is frequently made, but I have yet to see a single piece of evidence supporting it.
It's true by definition. Don't you believe in definitions?

I dunno, I haven't seen the inside of a science classroom in umpteen years. Maybe out in the hinterlands there is a cadre of atheistic biology teachers preaching a militantly atheistic explanation for the origin of the universe and life on earth in science class to all who will listen.
I rather think he's a figment of their imagination, sort of an urban legend, and that they never actually set foot in his classroom but, on the other hand, I have known a number of skeptical and/or atheistic scientists in my time and maybe sometimes they scoff to tender ears when it's not appropriate.
Fundamentalist Christians seem awfully sensitive to differing points of view, you may have noticed.
