I shall no longer be contributing to Stack Exchange, since it is clear that contributors are no longer valued or even treated with basic courtesy. Instead, you (alas, no longer we) are a revenue source, to be simultaneously exploited and lectured on politeness and inclusivity by cruel bigots. To all co-users, moderators and fellow-pedants, thank you and goodbye.

I also wish to make clear that all my contributions are licensed under CC-BY-SA 3.0. Any attempt to alter this unilaterally would be a clear breach of the licence terms, which would mean SE (or whichever body thinks that its convenience supersedes a legal agreement) no longer had any rights to this content.
