This story made me so angry that I swore out loud while reading it.
I try not to worry too much about the diversity of religious beliefs or political opinions that other people hold in good conscience. But I don't see the good conscience here. I don't understand what kind of conscience permits doing such a thing to small children, or to the professionals who do the hard work of helping children develop their curiosity.
I'm trying to imagine the public outrage that would occur if this tactic was used by Holocaust deniers, or by the idiots who think that slavery couldn't have been all that bad. ("Were you there?") Or, maybe, by AIDS/HIV deniers. ("Did you see the virus?")
And in the meantime, 2300 kids -- some of them "voraciously curious", and all of them at an age when they should be developing a sense of what civility means in an open, democratic society -- are being taught to shout down their teachers, disrupt the education of their classmates, recoil from the wonderful adventure that is the study of natural science, and thoroughly disrespect both learning and the work that it requires.
This man isn't just misguided -- he's an evil, egotistical, obstructionist ignoramus. And teachers don't get paid enough to have to endure this crap.
