A few years ago, Mel Gabler died, and I put up my response below. Now his wife, Norma Gabler, has also died. Good riddance at last. Those two did an awful amount of harm to American science education by inflicting their ignorant opinions on textbook selection in Texas.
I read this which led to this, where I learned a few months late that Mel Gabler was dead. This Mel Gabler. I don’t like to speak ill of the dead, but Gabler had a good 89 year run in which he spread poison and ignorance and lies, and made his wretched mark on the textbook industry. He was a dishonest old man who reviewed biology textbooks through the lens of his own stupidity and religious prejudice, and he was darned good at it.
