protesting over something so insignificant and inconsequential
Yes and no. The thing itself is small and inconsequential, but the subtext is a protest in favour of joining the EU and joining Schengen. The fact that relatively important EU-politicians are there to speech to the protesters makes that all the more clear.
(Imagine the opposite: like the head of the foreign affairs committe of Belarus talking to anti-governement-protsters in a EU-country. They’d be kicked out of the country immediatly and Belarus got themselves some extra sanctions.)
Fun fact! In the Netherlands, Elsevier publishes a weekly magazine about politics, which is basically the written version of Fox News for that country. Very nice that those people control like 50% of all academic publishing.
