Drexler seems to forget that anecdotal evidence cannot be used to justify the type of claims she's making in this book, which is riddled with biased sample and hasty generalization fallacies. Drexler makes sweeping statements about the efficacy of single mother parenting without even attempting to clearly define her definition, let alone establish a double blind study or make any other attempt whatsoever to compensate for her bias. Instead, she relies on anecdotal evidence supplied by individuals who were clearly selected based on whether or not their stories support her conclusions.
