I've been a faithful reader of Cox & Forkum for... well, a year or two, I guess; I have several times disagreed with their take on the issues, but I've only twice thought any of their cartoons came across as innappropriate. For satire this biting, that's a great record.
If you think the UN has anyone's best interest at heart other than the bureaucrats, if you think Bush is evil incarnate OR if you think Bush is infallible, this book is guaranteed to make you angry. If you're willing to actually think about things, it will change your mind on any of those three points (and probably others as well).
Oh, and I haven't seen any cartoon that was remotely racist, and Cox & Forkum are strongly ANTI-fascist, but hey, never let the facts get in the way of a good insult, eh?
