If there were no maccabi fans rioting and assaulting people the attackers simply felt were Palestinian or Muslim, then it would be peace in the street. Indeed, the responding violence seems to have been a predictable result of the initiating maccabi rioter violence.

Put yourself in the same position: A lynch mob from outside your community marches through it, masked and clad in black so as to be unidentifiable. Some of their racist chants are threats against you, your community, your family, your children. Other racist chants celebrate an ongoing genocide of your family, friends, and people. They vandalize your community and attack members of it along the way. It would not be unreasonable or unprecedented for your community to respond by stomping this lynch mob into the gutters, or at least running it out of town.
