An emerging theme from the reviews

An emerging theme from the reviews both here and on amazon seems to be that while individual reviewers have almost universally loved the book, and have taken from it the pure entertainment value I intended the book to supply, they are concerned that other people may be offended by it. So I'm wondering, who are these 'other people'? The only conclusion I've reached so far is that other people are always more delicate than we are, and that people who are easily offended by the nature of the human condition (or at least by the way I go about describing it) are going to be pre-put off by the blurb and will probably never pick up a copy anyway.
