I had a bit of a discussion online with a gentleman of the Swedish persuasion who did not like what I had written here. I told him that moral equivalence has its limits. Here's one example of a limit:
You say," said Lord Napier (confronted as Commander-in-Chief of the British Army in India by locals protesting against the suppression of suttee) "that it is your custom to burn widows. Very well. We also have a custom: when men burn a woman alive, we tie a rope around their necks and we hang them. Build your funeral pyre; beside it, my carpenters will build a gallows. You may follow your custom. And then we will follow ours."
