Like any of these people actually give a fuck about the businesses or people who reside there..
At face value my impression isnt so much that they care about the local business but more so what they view as a the decline of their country. Thats why i feel the slogan of "defund the police" perhaps is misleading. Most rational people will recognize the need for police, but would agree that the criminal justice system perhaps is long over due for a much need overhaul. How much of their reaction is from miss-information about the movement???
Also when have motorcycle gangs ever cooperated with or even liked the police, literally outlaw bikers and police have been on opposite sides from the beginning of the organization of biker gangs.
Like anything else, you only ever hear about the bad gangs. There are plenty of good groups that do everything from supporting vets to fundraiser rides for charity. I see the Christian motorcycle riders club (forget their exact name) all the time at motorcycle swap meets, they are normally there giving out free balloons and crafts to kids.
