This isn't that fucking complicated. You don't need to make some grand political stand. There's a pile of laws and by laws being broken, fucking enforce them and most of this problem will sort itself out. You have a noise ordinance (a db limit during the day, and a disturbance based system after 11pm), fucking use it. You have parking laws, enforce them, etc. This really isn't complicated. Like in most "movements", there's a whole lot of pretenders surrounding the real ones. The first goal is to dissuade those not fully committed from sticking around.
