Query: Biased, and therefore untrustworthy

Reading the book, it quickly becomes clear that the writers should make no claims to objectivity. The writing about Irish culture seemed strident and raw, as if written from embittered experience. I wasn't pleased to encounter profanity peppered into the descriptions, including the f-word and p-word. Sure, I'm a grown-up, but I thought this was a travel book? Then I encountered the text attacking the church, and the boxed section devoted to quoting and promoting a gay rights activist. Now, everyone is entitled to their opinion. But I bought the book for an objective take on Ireland, not to promote or read about the writers' political or social agenda. I wish I'd known what we were getting before my wife bought the book. I can't trust a guidebook that seems to revel in its own slant. We're giving the book away to Goodwill, and we'll rely on the other guidebooks we bought, like Rick Steves' (there are so many out there).
