Thats cute that you say opressing minorities because that decision (to put up the flag on that day) was made unanimously.

Yeah because the Bundestag voted for it (unanimously btw)

At least in Germany, and I imagine it would be similar in the Netherlands, it would be the parliament’s president because political symbols on clothing are not allowed.

That is particularly unfitting in this case though. Because the people that voted Milei are still in favour and the people that didnt are still against him. The people protesting are not the ones who voted him.
