They paint issues as black and white when there really is room for discussion. Do they not see the grey area? Is it more than they wanted to tackle? Thankfully I am reading this book in the context of a post-grad ethics class which provided opportunities for further analysis.
On another note, I resent the sexist remarks the authors make about Jenny McCarthy. She was a hack and I have no professional respect for her, but there's no reason to fall back on her personal choice to be a playboy bunny to demonstrate what an awful person she is. A woman can do what she wants with her body, and it in no way effects the quality of her work (I use "work" loosely in the case of McCarthy) positively or negatively. The remark is a cheap shot, and lends an unnecessary tone of misogyny to a text that will likely be read by many, many professional women (given that it's written for BCBAs).
