This book has some good information in it but it was a turn off when the author deals with gender and pronouns. She correctly states that to use "they" when referring to a singular person is incorrect. She advocates that singular pronouns also be avoided when the person to which it refers is unknown. She states that the use of the masculine pronoun in such cases is "offensive". This is a change in the rules of English grammer. She has allowed her feminist views to influence the book. I found this book distastful for this reason because I don't like this kind of propaganda and especially dislike the use of this book as a vehicle to promote the feminist agenda.
