First of all I agree wholeheartedly that the racist hooligans that instigated violence before the game and the slogans they chanted are absolutely despicable.
However the attacks against the Fans were not even indiscriminately against all fans (not just the hoolingans) but they were explicitly against Jewish people. Multiple reports from the situation after the game state how people were explicitly attacked for being Jewish. I don’t know how else to frame this than as an antisemitic attack.
Damn! That’s definitely a “I’m old” moment for me. I still remember when I first heard about the concept and I remember setting it up the first time on a self hosted project (which seemed harder back then).
Awesome project!
