Everyone is entitled to their customs
"General Sir Charles Napier was impeccably multicultural: 'You say that it is your custom to burn widows. Very well. We also have a custom that 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 the we will follow ours."
Reminds me of an editorial years ago entitled "In Defence of Cannibalism". Just another custom.
