Chiming in to say:
I really find distasteful some of the arguments that seem to be going along the lines of "BUT THERE ARE CHILDREN ON AMAZON". I've seen this argument utilized to argue that Amazon should basically sell nothing but *maybe* The Swiss Family Robinson, and even that's iffy because their farm animals get pregnant from time to time. (God knows how when they only have one cow with them. Maybe there's a wild bull on the island.)
Speaking as an adult (who doesn't, in full disclosure, have children), I'm tired of hearing that the whole world has to be child-friendly in order to protect the little ones from ever seeing, hearing, viewing, or being aware of anything beyond puppies and unicorns and the stork.
In order to have an account with Amazon for purchasing items, you have to have a credit card number. That account (with linked credit card) has a password that parents should not share with anyone, especially with their children. I'm okay if Amazon wants to modify the site so that "protected" items (erotica, dangerous power tools, the Oxford English dictionary, etc.) require you to be logged into the site in order to view them. Fine.
But removing books, movies, video games, lawn mowers, erotica, 3 Wolf Moon T-shirts, etc. just because THE CHILDREN MIGHT BE CORRUPTED? No. Just, please, no. I'm an adult and I don't want to live in a Disney movie, please.
