I once found a crazy website maintained by people who wanted Latin words in English to be pluralized as was proper in Latin. Their organization had some sort of name, and they derided some rival organization which was in favour of forming all the plurals with English rules instead. It was a little on the surreal side, partly because at first I wasn't sure what I'd stumbled on, and then I couldn't believe that people would devote so much time to such criticizing a tiny aspect of of such a big language!
