I don't acknowledge anything of the sort, and it doesn't help your arguments to put words in my mouth. Champagnes refers to wines made in the AOC of Champagne using the methode champenoise. This methode, and variations of it, are also used elsewhere. The combination of terroir and methode produces a particular style that lots of people value highly, although this doesn't include you. If you wanna keep drinking your prosecco, calling it champagne (which would piss the Italians off no end) and muttering darkly about how it's akshully much better value than "French Champagne" thankyouverymuch, you go right ahead. But pretending to yourself that your tastes and opinions are some sort of natural law and objectively correct, and that everyone else is objectively wrong, is just toddler behaviour, placing yourself at the centre of things. You're the centre of your own universe, but not mine nor anyone else's.
