How are EU nations maintaining their distinct cultures?

Answer 1

Each has their own cultures, and nothing can really change that. The culture of each country is well embedded in it, for thousands of years in many cases. While some countries may have some similar traditions and cultures, each country is different, and some are very different. The people are all different and those many cultures cannot be moulded into one. Each country does its own things and that in itself maintains its culture. They have different organisations maintaining aspects of their culture. Many of those organisations existed long before the European Union did.
