If I came to Israel as an American, got drunk and rowdy, vandalized property, assaulted a cab driver, and then started burning Israeli flags while chanting death slogans towards an ethnic/cultural group that composes a significant part of the population of the city in downtown Tel Aviv, would there be consequences?
Why is it that Israelis behaving badly abroad must not experience any consequences for their stupid actions?
I think THAT was the point the author was making. You're trying to make it into some ethno-racist trope about Arabs not 'belonging' in Amsterdam - which is par for the course of those espousing a racist Zionist ideology, obsessed with Bronze-aged fairy tales of where people 'belong' based solely on ethnicity or religion.
In the modern world (the one that Zionists want so desperately to be a part of, while spitting in the face of its ideals), we have a concept of diversity and multiculturalism. My neighbor is my neighbor and is as much a resident of the city as I am, especially since there's a good chance we both came from somewhere else as immigrants at some point in time anyways.
So, aggressive, belligerent foreign visitors attacking people and property in my city is an attack on MY CITY, regardless of the ethnicity of the locals that were attacked or the racial makeup of the city. The city will respond in kind.
The attempts to play this off as an 'Arab' mob 'out to get' Jews is ridiculous. This was Amsterdam citizens and their property under attack, and fighting back against foreign interlopers who had 0 respect for the country in which they were visitors, and were hostile provocateurs.
