It's not ironic that separate people (jiggawatts and US/UK nationalists) hold separate beliefs. But here's a thought. Are you ironic for being one person holding contradictory beliefs? I doubt you have the same contempt for all people who want to maintain their own culture. For example, I'm sure you don't think that New Zealand Maori who want to popularize the Maori language in New Zealand are whinging about it and you wouldn't describe Maori culture in quotes as "their culture", implying it's not really theirs or not really a culture.
