My response? Computers do what you tell them to. This is a glitch that involved human error, homophobic human error. Amazon needs to issue a clear statement that what happened was against policy, is being corrected, is being investigated and that they enjoy serving a broad spectrum of customers, including those interested in gay and lesbian topics. Others agree.
Could be. This does nothing to change that Amazon handed it badly and needs to issue some apologies/statements as noted above.
I also take issue with the assertion that trolling is some sort of public service meant to demonstrate flaws in assumed trust relationships. It's one more form of Internet bullying and harassment.
Public outrage is the Stick of Efficiency. Accidental bias is still bias and still creates a problem. This matter getting public attention in a manner that was largely civilized was useful. If it hadn't gone down this way, authors affects would still be trying to sort this out with Amazon a month from now, as demonstrated by several cases of books that were affected by this nonsense as early as February.
