Well, people have been advocating killing members of my own profession for centuries. Happens occasionally, but normally we just get mocked in beer ads.

I personally have no use for rap or hip hop no matter what the lyrics -- a jumble of angry noises, it seems to me. But in free countries we have to tolerate other people, even if they have extreme views and like to listen to pounding distortion.

BTW, I don't believe that it is illegal to own or sell The Anarchist's Cookbook in Canada. I once purchased a similar book for its comedy value -- it was about fighting a revolution in the streets and how to make home-made machine guns and such. Various police and military friends of mine hoped that any revolutionaries they had to face would use this book, as they would end up killing themselves before they even hit the streets.:)
