I'd argue that that diversity you claim for Europe has declined greatly in the last couple of decades. Wherever you go, local young people have been following the same global social media for long years now, which has had a leveling effect. Even among the language diversity, what people are saying in their own languages is often calqued on English.

In the 1990s and early millennium, opposing globalization (especially Anglo-American influence) and advocating for local culture was a common position on the European Left. Today that has disappeared almost completely, so much that people are likely to perceive it as a stance of the far-right.
