If the EU was as conformist / homo-cultural as you suggest, the cultural identity of constituent states would have long since disappeared.
Go tell someone in Florence or Sicily that, because they have been in EU since 1950, they are no longer Italian (or that they are somehow now culturally equivalent to a Dubliner). See how that works out for you.
