It's like posters are deliberately closing their eyes to the timeline of what happened in Amsterdam.
Firstly, the Maccabe fans assaulted people, damaged property, pulled down Palestinian flags and went about the city making a nuisance of themselves and being louts whilst shouting incredibly offensive things about killing kids in Gaza and how Arab should die.
Following this, some of the Amsterdam fans decided to get their own back, and one of the WhatsApp chats for this called for a 'Jew Hunt'. Unpleasant, and they shouldn't have brought race into it, and shouldn't have gone down to the level of Maccabe fans.
After the match, both sides were violent and assaults occured on both sides. The footage that is often shown which we were told was the Amsterdam fans attacking Israeli fans actually is the other way round and Reuters admitted their mistake in this. The Israeli fans were the instigators of the violence, not the Dutch ones.
Given this, and Maccabe's reputation for violence and unpleasantness (beating someone with a Palestinian flag unconscious recently, booing Arab players in their own team, making monkey noises at Black players, chants encouraging rape, chants laughing about killing kids, chants that the IDF should kill Arabs etc), I have no qualms about banning them from the game. Other teams have been banned for far less.
