I only used the word "evil" to distinguish malicious, speech-suppressing censorship from activities which are technically censorship, but which are not malicious and do not suppress the freedom of speech. Clearly Amazon is engaging in the latter, not the former, and there is nothing wrong with that.
Unfortunately amazon has such relevance in today culture that the effect of their censorship is just nominally different from a violation of first amendment from the US government.
The first amendment does not mandate that private companies be forced to sell particular books. In fact, you could argue that the first amendment explicitly lets them not sell particular books!
At any rate, I was not saying that Amazon is trying to remove any book that happens to mention rape. I was saying that from what it looks like with this incident, they're trying to keep their store image clean by removing books with titles referring to rape. This is wholly different from censoring any mention of gay sexual violence with the intent to prevent any customers from ever reading any book that might refer to that subject.
But by using such a broad brush that is censorship, Amazon is basically answering them , "because I say so", which summed with the point I've made before, creates an ugly, ugly precedent.
It is hardly an "ugly, ugly precedent" for a company to be allowed to decide what products it sells, regardless of whether some subset of their customers want to buy those products. Do you think Amazon should be forced to make available every single book that is conceivably available on the market? Where do you draw the line? Why is that line any better than letting them draw the line based on earning a profit, which is their responsibility to their shareholders?
Don't confuse what Amazon is doing with the issue of freedom of the press. Amazon is not demanding that these books not be printed. Amazon is not demanding that these books not be sold elsewhere. Amazon has simply decided that they do not want to sell the books. This is no different than if a national brick-and-mortar bookstore decided they did not want to carry gay rape fantasy novels in its stores; certainly nobody would be complaining about censorship if that happened.
I would argue that a far uglier precedent would be to force Amazon to sell books they do not want to sell. It's a very short step from there to forcing publishers to publish books they do not want to publish, and you can probably see why that would be a bad thing.
You may not agree with Amazon's moral decisions on which products they sell, but it is absurd to claim they should not be allowed to make those decisions.
