This is utter nonsense, so completely removed from reality.
Countries in the EU are not losing their national identity or culture, not even remotely. I'm guessing you have never been anywhere near an eu country. My country has been in the EU for 50 years this year. Our identity has not changed in that time, we haven't lost our culture and we are definitely still as proud as ever.
You have been reading or watching something crazy, it's making a fool of you.
