I'm not claiming a 'right' in that regard; however, I am saying that in running a legitimate business, which violates no laws, there is nothing preventing Amazon from doing this.
And let's take your Germany metaphor one better - how much worse off would we be if "Mein Kampf" had been censored? If we weren't tipped off to just how bad Hitler was?
So let's get back to my other question: are you ready to go after the publisher and the author of this trash?
Except an teensy, tiny ounce of morality and concern for the well-being of children...
Mein Kampf aside (one would have to get into specifics of that book), if someone wrote books promoting the annihilation of a particular race of people, like African-Americans, you know in a minute that Nambalazon would not (rightfully) sell such (and there would be an immediate uproar in our society). Or if someone wrote a book supporting the idea that all homosexuals should be elimnated, the same would (rightfully) ensue. But when it's the promotion of child rape, I guess it's a different story. Kids are used and abused, sexually and otherwise, in today's society. And we don't have the cojones to fight against such by every means available. Shame on us. And shame on virtual child molestor Jeff NAMBLA Bezos.
