Anyone besides me thinks it's kind of weird that the EUropeans are all into the European championships when they are trying to erase their own countries identities with on big European country.
Oh dear, what an ignorant comment. Please stick to running.
It's not an ignorant comment. People are proud of their identities. For thousands of years, people put themselves in little clans/tribes etc. Now that the world is global, a lot of that is being lost. Why do you think sports are so freaking popular?
You root for your local town.
You are right that the European cultures are being erased, but not by the European Union per se, but by mass migration. That's why you will see a lot of African athletes in these "European" championships. And that's why the Brits voted for the Brexit.
